Re: [otb-users] Orthorectification models
Hi, Most of the sensors supported in OTB use a RPC based model (used during orthorectification). Notable exceptions are Spot5 and Sentinel 1 which use a more rigorous model.

Re: [otb-users] gap filling Filled data with 0
Hi,
You are referring to the "Image Time Series Gap Filling" right ?
Does your output carry a no-data information reported by gdalinfo

Hi,
I recently changed of computer. In my old

procedure described here :
https://www.orfeo-toolbox.org/CookBook/Installation.html.
When a was running the Gap Filling operator it was OK, no
problem to report.
On my New Centos machine, OTB was already
installed probably with the same procedure as before, and
the version is 6.4. Now, when I 'm
running the Gap Filling operator (with same inputs as on my
old machine), I have strange results, and it seems that
masked values (defined by the mask) are converted to 0 value
in the output.
I don't know if the problem come from the
version, so i tried to uninstall the 6.4 version and to
re-install the more recent version 6.6.1, but the result is
the same.
Any idea ?
Thanks in advance for your help.

Re: [otb-users] Stereo processing
Maybe check your disparity range. Note that the settings minhd,
maxhd, minvd maxvd are disparities from left to right:
right_position = left_position + disparity
For instance, horizontal disparities are expected to be negative
in a classic stereo-bench : objects on the ground are expected
with a high disparity (around 0 pixels) while objects higher than
the ground are expected with a negative disparity.

Guillaume

Re: [otb-users] OTB 6.6.1 TrainingImageClassifier issue on new images
The purpose of the shapefile is to select some polygons and tag them with class labels, so that the application knows where to pick pixels to train itself. If you want a shapefile of the whole image footprint, you can use the output of ImageEnvelope application. About projections, maybe have a look at tools such as gdalinfo and ogrinfo they are great to have relevant information on images and shapefiles. If you want a reference about projections, you can check http://epsg.io/ Regards, Guillaume On 12/20/18 5:51 PM, bogdanul2003 wrote: Hi, I've tried different shapefiles with dimensions rangeing from a small part of the image to the entire image.

Re: [otb-users] Advice on Raster algebra with OTB
Hi Agustin,
The BandMath tool only processes the images of equal sizes. So I
would go with creating an image with repeated lines, and I think
the VRT format can do that.
After a quick search here, I think
you can create :
a VRT with the size of A,
put inside a single 'SimpleSource' which is your one-line
image B
set the 'DstRect' parameter to the full dimension, it will
stretch the one-line image to fit the full image
you tell GDAL to use nearest neighbor interpolation :

Guillaume

that is:
multi-spectral image A: x rows, y cols, z bands

I would need to divide each row of A by B.
In a simple notation:
res <- a
for(i in 1:nrow(a)){
res[i,,] <- a[i,,]*b
}
I'd like to this for relatively large images (x=969, y=640, z=224),
avoiding any loop if possible.
The most obvious strategy would be to create a b2 image by repeating the
row of b x times and then use the otb raster arithmetic for a/b2. But is there
an otb way to create such a b2? or perhaps another approach (I.e using
the BandMath tool?)

Re: [otb-users] Stereo processing using OTB for DEMOIS-2
Hi,
It looks like the subsets you used don't have a correct
localisation. What did you use to make the subsets?
To enhance the disparity map, you can try the median filtering
option. When you convert the disparity map into a DEM, you should
also keep in mind that setting a DEM pixel size larger than the
original sampling distance will allow to compute elevation at each
pixel using several 3D points. If you set the DEM pixel size to
exactly the resolution of the input image, you will have a lot of
cells with 1 or 0 3D point inside.
Regards,
Guillaume

Hello Sir,
I am trying to stereo process the stereo pair using OTB.
The actual elevation of the area ranges between 300-600 m.
When I processed stereo for full image I got the same
elevation ranges. but for subset Im getting very low values
between 20-100m. Actually stereo processing for full image
taking lot of time approx 24 hrs. Which makes difficult to
analyse different parameters. Please suggest better option to
analyse.
The DEM is having lot of no data values after converting
disparity to elevation map. Is there any technique in OTB to
fill the data.

Re: [otb-users] Orthorectification for WV3/4 ?
Hi,
Basically, if OTB is able to read the RPC coefficient on your
WV3/4 product, you can use Orthorectification. You can check this
with application ReadImageInformation. I don't have a sample
sensor product yet.

Guillaume

Dear colleagues,
I am curious if the orthorectification module already works

Re: [otb-users] Zonal stats: updating polygons of a vector file by adding fields computed from a raster
Hi, I don't see anything in OTB that does exactly what you need. The approach you propose seems the right one. I see two other ways : Build a new filter using the Sampling framework. You may re-implement the ThreadedGenerateData() to use your thread pool. ImageSampleExtractorFilter is a good starting point. Using existing OTB filters. Iterate over polygons, for each one : copy it alone in a in-memory OGRDataSource extract an ROI of the image over the polygon extent rasterize the polygon in a binary mask over the input image ROI with ManageNoData, apply the binary mask as a no-data on the input image ROI use ComputeImagesStatistics with the background value corresponding to no-data store the results in the current polygon. My 2 cents, Guillaume On 08/03/2018 05:34 PM, Jordi Inglada wrote: Hi, Given an image (raster) and a vector file containing polygons, I need to compute a series of values for each polygon like the mean of a particular band of the raster, etc. and then produce a new (or update the) vector file with new fields. I think these are called zonal statistics. It looks like the LSMSVectorization application does that, but it uses a raster segmentation instead of an input vector file. Given that my polygons cover only a small fraction of the input raster, I don't think than rasterizing the vector file to use this application will be efficient. An besides, I would have to link back the attributes to the original polygons, which is an additional step. Is there any other way to do that with existing OTB applications? Maybe gdal command line tools can do that? I have been looking around and it seems that this is usually done the way LSMSVectorization does it (burn the vector to raster, then compute using rasters only). Do you have any advice on how to proceed if I need to write my own application for that? I guess I will have to if I want to be able to compute other features than mean and variance of the raster bands. By the way, my images and vector data are huge, so streaming and multi-threading will be needed. I was thinking about the following approach: 1. Read in a set of polygons until a total surface is reached (so that we can associate that with the RAM needed for the total number of raster pixels to keep in memory). 2. Project the polygons onto the raster geometry and read in the pixels 3. Parallel computation of the stats (either with an OpenMP loop or a simple thread pool [1]) 4. Write the geometries and the stats to the output file 5. Release the memory and go back to 1 Any comments on that? Thanks.

Re: [otb-users] DEM file in training for classification
Hi,
In fact the DEM is not always used. It can be used if your input
image and training vectors are not in the same projection. For
instance, if you use a sensor image and training vectors projected
in WGS84, the application will have to convert the polygon
coordinates from WGS84 to your sensor frame, hence the need of a
DEM.

Guillaume

Re: [otb-users] efficient use of hardware resources by OTB
Hi, First thing to know is that during TrainImagesClassifier, some parts of the processing are mono-threaded (only 1 CPU used). This is a design limitation. However, the multi-threaded parts of this application should be able to use all the CPUs available. About the memory consumption, the RAM parameter in the application should set the maximum RAM amount to be used. I think that in the case of TrainImagesClassifier, this setting is difficult to derive because it depends on the polygon density in your training/validation vector layer. If you use an other application that is more like an "image to image" processing, you should see the expected behaviour more clearly.

Re: [otb-users] Segmentation of raster stacks with Orfeo toolbox
Hi,
In OTB, segmentation algorithms use multi-channel images to
perform the segmentation. The similarity between pixels is
computed based on a spectral distance (taking into account all the
stacks, as spectral bands). It doesn't compute a mean layer.
Hope it helps,

Re: [otb-users] ITK configuration file for cmake (Windows compilation)
Hi,
Depending on your install of ITK, you can set the variable
ITK_DIR in the OTB build configuration. This variable should
contain the path to the folder containing ITKConfig.cmake. For
instance, if you use OTB binary package, it should be something
like : .../OTB-6.2.0-Win64/lib/cmake/ITK-4.12

[otb-users] OTB 6.2.0 Released
Dear all, We are pleased to announce that Orfeo ToolBox 6.2.0 is out ! As usual, ready-to-use binary packages are available for Windows, Linux and Mac OS X: You can also checkout the source directly with git: git clone https://g...@git.orfeo-toolbox.org/git/otb.git OTB -b release-6.2 We welcome your feedback and requests, and encourage you to join the OTB community and mailing list. If you think you face a bug, please report it on Mantis. As we made an exception to our 3 months release schedule (OTB 6.0 is now 6 months old), we know that you are all looking forward to updating your favorite tool. And there is indeed a lot of new things in this new version. In addition, a total of 47 reported bugs have been fixed. You can check the Release Notes . Better help, doc and logs Thanks to RFC 91, errors have been made clearer everywhere in OTB. For instance, when OTB 6.0 used to say: 2017 May 16 18:07:49 : Application.logger (CRITICAL) Invalid image filename blabla.tif. 2017 May 16 18:07:49 : Application.logger (FATAL) The following error occurred during application execution : /home/otbval/Dashboard/src/OTB/Modules/Wrappers/ApplicationEngine/include/otbWrapperInputImageParameter.txx:79: itk::ERROR: InputImageParameter(0x2158710): No input image or filename detected... OTB 6.2 now says: 2017-05-16 18:07:49 (FATAL): Cannot open file blabla.tif. The file does not exist. RFC 96 takes care of improving the display of help in command-line mode. There is now a -help switch that allows to display the same help as in the documentation tab of GUI applications, and this switch also allows to get help for parameters: $ ./bin/otbcli SampleSelection -help instats sampler vec MISSING -instats Input Statistics (mandatory) Input file storing statistics (XML format) -sampler Sampler type [periodic/random] (mandatory, default value is periodic) Type of sampling (periodic, pattern based, random) MISSING -vec Input vectors (mandatory) Input geometries to analyse Meanwhile, we started a background task for improving the content of the documentation itself. With a single sprint of one day, we already improved greatly the documentation of 19 applications, which can are listed in RFC 103. We are planning to continue this work in future releases until all applications have been screened for documentation improvements. Other improvements in this section includes the logging for composite application (RFC 105), and an explicit open-source licence for the Cookbook (RFC 94). Improvements and refactoring of several applications We re-factor several applications following discussions during last OTB User Days: KMeansClassification: now a composite application of sampling/classification applications which use internally the KMeans implementation available in the Shark library ExtractROI: allow to define different types of ROI (coordinates in latitude/longitude), give point of interest and a radius, use a reference vector… All in one LSMS segmentation application: new composite application LargeScaleMeanShift which combines all steps of Large Scale Segmentation in one application! Convert : new RGB mode to select input bands (can be read also automaticcally from the metadata) PixelValue: Add new way to input pixel position DownloadSRTMTiles: complete revamp of the application which allows to define tiles area from images/vector/list of tiles, better handling of corner cases Improved build, superbuild, and packages There is now only one binary packages per platform which includes: All in one: All OTB applications, Monteverdi and all official remote modules which are now packaged in the same archive (no more distinction between OTB and OTB-Contrib package) OTB XDK: OTB package contains now headers and development files which allows to compile and link your source code with OTB. Moreover, superbuilds now contains the latest OpenJpeg, Gdal and NetCDF5. Welcome to Daniel McInerney We’ve got one new committer to OTB! Daniel is a researcher working for Coillte Teoranta – the Irish State Forestry Board and a user of OTB for a long time. His first pull request includes a lot of great improvements in the documentation. I encourage anybody interested to get more involved in OTB to join discussions and become part of the team. Orfeo ToolBox Graduates OSGeo incubation! OTB has graduated in July from incubation and is now a full fledged OSGeo project! Graduating
[otb-users] OTB 6.2.0 release candidate
Hi, The OTB Developer Team is pleased to announce that the version 6.2.0 Release Candidate is out ! For this release the delivered binaries contain : OTB binaries : monteverdi, mapla, OTB libraries and applications, applications launchers, python wrapping, ... The dependency stack (GDAL, ITK, ...) The necessary headers to use the package as an XDK : you will find OTB headers as well as dependencies headers Some official remote modules are included in the package, like the previous "-contrib" packages. Now there is a single flavour containing all. The binaries are available at the usual place : https://www.orfeo-toolbox.org/packages/ Please note that the Linux binaries require a recent platform. This is a known issue and for the final release we plan to deliver binaries with a better compatibility. If you want to get the sources : git clone http://g...@git.orfeo-toolbox.org/git/otb.git OTB cd OTB git checkout -q --detach 6.2.0-rc1 Feel free to give your feedback, report bugs and strange behaviours : https://bugs.orfeo-toolbox.org OTB-DevTeam -- Guillaume PASERO Responsable technique Business Unit ESPACE & GeoInformation - Département Payload Data & Applications CS Systèmes d'Information Parc de la Grande Plaine - 5, Rue Brindejonc des Moulinais - BP 15872 31506 Toulouse Cedex 05 - FRANCE +33 561 17 64 21 - guillaume.pas...@c-s.fr -- -- Check the OTB FAQ at http://www.orfeo-toolbox.org/FAQ.html You received this message because you are subscribed to the Google Groups "otb-users" group.

Re: [otb-users] OTB6.1, openCV and RandomForest
Hi, The file "otb_opencv_api.h" is generated from "otb_opencv_api.h.in" when compiling the OTB : if you use opencv 3 then OTB_OPENCV_3 is defined, otherwise, the file is empty. Could you give some details on how you compile OTB? Your working model file seems to be generated by OpenCV 2.

I had an error compiling RF forest classifier due to the compiler not finding otb_opencv_api.h. It could be solved by adding the path of the include dir with ccmake, but I wonder what is the purpose of this file: it seems to set a variable OPENCV_3, but it is not actually checking if open_cv v3 is there (in my case, I use an external open_cv3). Now it gives me a systematic segmentation fault (on previous version, I had sometimes a segmentation fault, but not always, and I was hoping that the next version would solve the problem). The problem seems to come from my training step: I can run the models of my previous version with otbcli_ImageClassifier, but it doesn't work with the new models (which has a different structure, see below) NOT working %YAML:1.0 opencv_ml_rtrees: is_classifier: 1 var_all: 5 var_count: 4 ord_var_count: 4 cat_var_count: 1 training_params: use_surrogates: 0 max_categories: 10 regression_accuracy: 9.997764825821e-03 max_depth: 15 min_sample_count: 25 cross_validation_folds: 0 nactive_vars: 0 global_var_idx: 1 var_idx: [ 0, 1, 2, 3 ] var_type: [ 0, 0, 0, 0, 1 ] cat_ofs: [ 0, 0, 0, 0, 0, 0, 0, 0 ] class_labels: [ 1, 6, 7, 12, 13, 17, 19, 22, 24 ] missing_subst: [ 0., 0., 0., 0., 0. ] oob_error: 2.4000992032737081e-01 ntrees: 75 WORKING %YAML:1.0 my_random_trees: !!opencv-ml-random-trees nclasses: 9 nsamples: 88071 nactive_vars: 2 oob_error: 2.4195188071840054e-01 ntrees: 75 is_classifier: 1 var_all: 4 var_count: 4 ord_var_count: 4 cat_var_count: 0 training_params: use_surrogates: 0 max_categories: 10 max_depth: 15 min_sample_count: 25 cross_validation_folds: 0 priors: !!opencv-matrix rows: 1 cols: 9 dt: d data: [ 1., 1., 1., 1., 1., 1., 1., 1., 1. ] var_type: [ 0, 0, 0, 0 ] cat_count: !!opencv-matrix rows: 1 cols: 1 dt: i data: [ 9 ] cat_map: !!opencv-matrix rows: 1 cols: 9 dt: i data: [ 1, 6, 7, 12, 13, 17, 19, 22, 24 ] trees: -- -- Check the OTB FAQ at http://www.orfeo-toolbox.org/FAQ.html You received this message because you are subscribed to the Google Groups "otb-users" group.

Re: [otb-users] SPOT 6/7 orthorectification
Hi,
To my knowledge, Spot 6/7 is supported. The geometric model is
based on the RPC coefficients from the DIMAP.
You could try to investigate if the bad accuracy comes from DEM
settings :
run Orthorectification without any DEM
run Orthorectification using standard SRTM tiles (.hgt files)
Just a note on the opt.gridspacing parameter : it corresponds to the
step of the resampling grid, expressed in the units of the output
projection system (if you are using the default UTM projection : it
means 4 meters).
Regards,
Guillaume

Are Spot 6/7 data supported by OTB Orthorectification app ? I
guess as it's the same dimap format as Pleiades.
My parameters hereafter :
-io.in the jp2 file in the dimap folder + extended filename
skipcarto=true
-io.out output tif file
-elev.dem directory of the geotiff DEM file (EPSG:4326)
-opt.gridspacing 4
I tryied also to play with rpc option parameter but
unsuccessfully.
It should work better, I get reliable results from a commercial
software (also based only on RPC coefficients and without GCP).
How can I improve the result ?

Re: [otb-users] Re: I can't start otbApplication. AttributeError: 'NoneType' object has no attribute 'GetParametersKeys'
In the Linux standalone packages, you can find a file
"otbenv.profile".
There is a few lines specific to the standalone package (such as
the section "OTB_USE_SYSTEM_GTK").
The variables GDAL_DATA and GEOTIFF_CSV are there because the
package uses a specific GDAL build (should not be needed with a
system GDAL).
The PYTHONPATH and OTB_APPLICATION_PATH are used to properly
setup python wrapping and application path.
In your case, modifying the PATH should not be necessary if you
install OTB under /usr or /usr/local.

Re: [otb-users] traitement d'image avec OTB 5.10
Hi Jérôme,
This mailing list is in english so my answer will be in english
as well.
I guess every one has its own recipes to select training areas.
Your goal is to have training areas that are pure (only 1 class
per region), and that show enough diversity to characterize your
classes all over the scene.
After doing the training step, you can validate the model with a
ground truth and compute the confusion matrix. See OTB
applications like TrainImagesClassifier and
ComputeConfusionMatrix.
Also more information here :

Re: [otb-users] Simple geometry tools in OTB?

The OTB already has an application to assess a RPC sensor model based on GCPs.

Also, is there a tool in OTB to actually fit such a rational polynomial with prescribed denominators? No, at the moment there is no way to estimate a polynomial transform based on GCPs.

Re: [otb-users] Re: readlink: illegal option -- f in otbcli_LSMSSegmentation (OTB-5.10.1)
This is a difference between BSD and GNU implementations of
readlink command. I will try to find a more portable solution.
This comes from the file otbenv.profile , line 9 :
You can replace it by :
OTB_APPLICATION_PATH=$(cd "$OTB_APPLICATION_PATH"
2>/dev/null && pwd -P)
The behavior of pwd -P is the same on linux and MacOS.

Re: [otb-users] Re: Extended filename for band selection
Dear Julien,
Thanks for your feedback.
It is true that current syntax is somewhere in-between different
standards.
About the use of "band[]" as general syntax, it would not be
consistent with other extended filenames : we always use
"keyword=value". So, it should be something like "band=[]".
Regards,
Guillaume

Dear Guillaume,
This would be usefull, thanks. I don't care about band or bands.
for the syntax, Python-like is nice, but then it is confusing
not to start with band 0 for the first band. maybe using []
would also make things clear. To be more "pythonic", I would
rather use bands[] with the python indices but this is probably
more difficult to parse. Also, in python, [2:4] would mean bands
with index 2 and 3 (not the 4), so this is not consistent.
To conclude, Python-like is fine, but it would be very confusing
if there are too many differences. In your example, it makes me
think of Matlab indexing, which is fine but should be stated as
such in the help (then use "end" instead of -1 for the last
band)
For the last question, I do have some home made scripts that
could benefit from band selection in the extended filename. One
application with a standard filter would be the use of Meanshift
segmentation where you only want the smoothed mean value for one
of the output bands (e.g. a NDVI band) but you want to use more
than one band as input for the mean shift segmentation.

Dear users,
A new feature is in development to provide an extended
filename for input band selection (see extended_band). A simple use-case is when you
have a multi-channel image, and you want to process only
the second band of this image using an OTB Application.
With this feature you could do it like this :
otbcli_MyApplication -in "my_image.tif?band=2"
-out output.tif
The current syntax (inspired by Python syntax) has already
been implemented :
band=r1,r2,...,rn where each 'ri' is
a generic range
A generic range can be :
A single band index : '1' is the first band, for
negative numbers the numbering is backward ( '-1'
is the last band)
A range of bands, using the character ':' between
optional start and end indexes :
'3:' means the 3rd band until the last one
':-2' means the first band until the second
to last
'2:4' means bands 2, 3 and 4
We would like to have your feedback on several points :
We will likely change the keyword "band" to
plural "bands", no objection ?
Is the syntax clear / convenient / confusing ?
There can be a debate between 0-based and 1-based
indexing for band numbers. At the moment, it is not
uniform in OTB but we think that 1-based indexing should
be the convention exposed to the user.
It is also possible to implement it on image writers,
would it help ? What would be your use-cases ?
Thanks for your feedback,
Guillaume

Re: [otb-users] NDVI at 0
Hi,
I don't quite understand what you want to do : train a
classifier at each date using either landsat bands or (landsat
bands + ndvi) ? If yes the normal process would be to compute the
NDVI of each L8 image and stack it to the corresponding L8 image,
so that you have a time series of (L8+ndvi) images. But you can
also stack all the dates together and then use the right field
names to perform training.
The band numbers to compute NDVI should correspond to the band
order of your L8 images (for otbcli_RadiometricIndices,
first band is band 1). It seems correct.
What are the values of variables ${bands} and ${ndvi} ?
In the stack 'alldates2014_avignon_landsat.TIF', you should compute
correctly the field names to use.

Hi,
When you want to perform the training, the "feat"
parameter should be fed with field names from
training_samples.sqlite on which you want to train.
In your pipeline, you should concatenate your NDVI images

Re: [otb-users] Stereo Rectification Grid Generator
Hi, This "epi.step" is the step at which the deformation grid (to resample into epipolar) is computed. The computation of these grids are not streamed nor multi-threaded, the whole grid will be allocated in memory (sadly there are still some filters like this in OTB). I don't think the mpirun will help in this particular case. For large images, it is advised to use a step larger than 1. If you use a smooth or low-resolution DEM, the transform between sensor and epipolar space will be quite regular, so you can afford computing this transform 1 pixel every 5.

Re: [otb-users] statistics
Hi,
If you only have 1 sample in some classes, it will be difficult
to perform the SampleSelection using the modes "smallest" or
"constant". However, since your total number of samples is not
huge, you could select "all" the available samples.
As you proposed, you can also remove these small classes from
your shapefile (or maybe fuse them with similar classes).
Regards,
Guillaume

Re: [otb-users] Re: segmentation watershed
Hi,
The segmentation filter tries to identify homogenous regions. In
otbcli_Segmentation , the image first goes into a gradient
magnitude filter before watershed filter.
The watershed filter itself is documented here:
https://itk.org/Doxygen48/html/classitk_1_1WatershedImageFilter.html.
You should try to use it directly.
Hope it helps,

As part of this process, I've been adding and removing

For example the classifier makes decisions and groups

Band 3- 50%
Band 4- 15%
Having this information will allow me to remove less

Is this a possibility? Or is there a comparable

Re: [otb-users] Rasterization with python bindings
The standalone OTB build uses its own GDAL version (2.1.0, even
if you don't call otbenv.profile) so the GDAL_DATA has to be set
accordingly. Yes I advise you to source otbenv.profile every time
you use python binding, otherwise GDAL will try to read data files
on the system (somewhere in /usr/share/...) that don't match its
version.

Re: [otb-users] How to use the vector from segmentation to classify an image?
Hi,
You should use TrainVectorClassifier instead of
TrainImagesClassifier. This will train and produce a SVM model
("-io.out" output file). You will have to set (at least) :
Input Vector Data (io.vd)
Output model (io.out)
Field names for training features (feat)
Field containing the class id for supervision (cfield, in your
case it will be "training")
Classifier to use for the training (classifier = libsvm)
However, before using this application, you will have to prepare a
vector dataset with only your training polygons (polygons with a
missing value in the field "training" will make the application
crash).
Once you have the output model file (simple text/xml file) you can
use it to do the classification on the full dataset (using
application OGRLayerClassification).

Guillaume

Hi Patricia,
If I understand right, you want to perform
object-based classification.
In OTB-5.6.1 there is the application
TrainVectorClassifier to train a classifier based on
input geometries. You have to set several fields in
the geometries you want to use for training :
- one field to indicate the class of the geometry
- several numeric fields to store the features
attached to geometries.
The fields can be extracted from a raster with
LSMSVectorization and modified with QGis.
After the training, you can either apply the model on
the full set of geometries (with OGRLayerClassifier),
or try to apply it on a raster (with ImageClassifier,
but more difficult).

Re: [otb-users] How to perform automatic contrast enhancement and color correction ?
Hi Léo,
In OTB there is an application to perform basic conversion :
otbcli_Convert.
This applications allows to convert the dynamic of an image to an
output pixels type (linear and log transform supported). It will
compute min/max for each band and stretch this dynamic to the
output range of your destination pixel type (i.e. 0-255 for
uint8). By default, 2% of the histogram are cut on each side (can
be tuned). You can also supply a mask to discard pixels during the
histogram computation (can be useful for clouds).

I 'm currently working on Pleiades Datasets, and i would like to
perform automatic contrast enhancement and color correction, and
i would like to know if anybody know a workflow to do that...
I would like to reproduce a thing like "OVR" from Pleiades Data
distributed by Airbus Defense & Space.
I experimented software like Image magick with this kind of
code:
convert -monitor -modulate 100,130 -channel R -gamma 1 -channel
G -gamma 0.95 -channel B -gamma 0.875 -channel RGB
-sigmoidal-contrast 11x40% %OUT%BUNDLE_ORTHO_RGB.TIF -compress
lzw %OUT%BUNDLE_ORTHO_RGB_CC.TIF
It's not bad but, i spend lot of time trying to find the correct
parameters... And i don't know how to calculate them
automatically.
A good software (but not open source) do a thing like that:
Spectral discovery (by Geosage, an Australian company), this
software perform L8 pre-processing (for data visualisation
only): this soft read metada (MTL files, like DIMAP for
pleiades), to estimate parameters for stretching, and scaling to
produce a good looking L8 RGB tiff. I think it is possible to do
that with the dimap but i don't know how...
I have read a good paper about color correction for sat imagery:
An Inquiry on Contrast Enhancement Methods for Satellite Images
They speak about to very good algo: MSR (Multi Scale Retinex)
and LCC (Local Color Correction), but i don't know how to
aplly them on my Pleiades dataset.
If anyone want to share about contrast enhancement and color
correction, i am very happy to share my ressource.
Thank you for your time

Re: [otb-users] Re: Installation of OTB on Eclipse neon C++
Hi,
Indeed, OTB uses CMake to compile libraries and executables. Here
is the workflow :
You give CMake all the details on your build : build type,
path to dependencies, various compilation options,...
CMake configures the build folder and generate standard
makefiles (can vary depending on the platform and the chosen
generator)
run 'make' to compile.
Maybe these pages can give you some hint :

Re: [otb-users] OTB with bash under windows OSGEO4W
Hi,
The correct order is "otbApplicationLauncherCommandLine $cmd
$sopath $*" (maybe a typo).
The second argument "$sopath" is used to find the directory
containing the application dlls ("otbapp_MyApplication.dll" ...
there is 1 dll for each OTB application).
Do you still get the DLL error ?

$cmd contains an OTB application name

I'm not sure about what i should put in the sopath variable

out how to force the use of the last OTB version i installed
in another directory.
Many thanks for your help

Re: [otb-users] Re: Using standalone binary for dev purposes (C++)
Hi,
The standalone package just contains binaries.
You can either use OTB SuperBuild to compile all dependencies, or
you can also give a try to a Linux XDK :
https://www.orfeo-toolbox.org/packages/xdk/OTB-5.9
It contains libraries and headers for all OTB dependencies,
without OTB itself.

Guillaume

Re: [otb-users] Error while monteverdi run on centos 7 OTB-5.8
Hi,
Then I think you are facing a known issue with remote desktop
environments (https://bugs.orfeo-toolbox.org/view.php?id=1278). We
have a fix ready, but it has not been integrated for release 5.8
If monteverdi works fine with your Ubuntu 14.04 VM, it could be
that the configuration of the graphics driver is different in
VMWare. Maybe something to dig.

Re: [otb-users] NDVI at 0
Hi,
When you want to perform the training, the "feat" parameter
should be fed with field names from training_samples.sqlite on

In your pipeline, you should concatenate your NDVI images into
one stack ( otbcli_ConcatenateImages) then use this stack to
extract the samples values (otbcli_SampleExtraction).

Re: [otb-users] Atmospheric correction of Landsat 8 thermal bands
Hi Agustin, In OTB, optical calibration is implemented to retrieve : luminance then TOA reflection then TOC reflection The last 2 levels don't apply to thermal bands, but if the metadata of TIRS product is read correctly (not tested ...) you should get the first level. There are also coefficients to translate into surface temperature I guess, this can be done with a BandMath and the right formula.

Hi,
It seems that you trained you model 'model.rf' with a certain

You can check the parameter 'var_count' in your file 'model.rf'

[otb-users] Status of Ice and Monteverdi2 git repositories
Dear all,
The source code from Ice and Monteverdi2 repositories is now
integrated into OTB repository (see Modules/Visualization). These
components will be maintained within the main OTB repository,
which makes the previous repositories obsolete. If you are still
using them, don't be afraid, they will not be removed right away.
They are still needed to build OTB version 5.6 and older. If you
are using the trunk of OTB and Monteverdi2, you have at least 2
options :
Build OTB with monteverdi enabled (for this you need to switch
on several third parties such as Qt4, Glew, OpenGL, Qwt). Then
monteverdi & mapla will be compiled in OTB build directory.
No need for a separate build of Monteverdi2 repo.
Build OTB without monteverdi enabled, and compile Monteverdi2
as a separate build (this solution is experimental).
Starting from next OTB release 5.8, monteverdi and mapla will be
compiled from the main OTB repository. As they are now completely
synchronised with OTB, their version number will also follow OTB
version :
OTB 5.6 -> Monteverdi 3.4 & Mapla 3.4
OTB 5.8 -> Monteverdi 5.8 & Mapla 5.8
If there is no strong objections, the nightly branch on Monteverdi2
repository won't be updated anymore.
Regards,
Guillaume

Re: [otb-users] OTB PostgreSQL API
Hi,
In OTB, almost every image is opened using GDAL. If you manage to
have GDAL reading from a PostGIS database, it should be
transparent on OTB side.
More information here: https://trac.osgeo.org/gdal/wiki/frmts_wtkraster.html
The same goes for the shape->PostGIS, if you can directly output
the vector segmentation in a PostGIS table, it should be faster. (http://www.gdal.org/drv_pg.html)
About the LSMS Smoothing performance, there may be a way to improve
the situation with the parameters exposed in the application.

Guillaume

Hi all,
I am performing segmentation on many Landsat8 scenes stored in
PostgreSQL / PostGIS. I have a very sub-optimal work-flow (all
is done in Python script on server side):
export tiled raster from PostGIS to .tiff image
perform 4 steps of LSMS
segmentation using python API resulting in .shp with
segments
import this with shp2pgsql back to table in PostGIS.
Although this is working it has several drawbacks
I have found that first
step of LSMS is not linear regarding elapsed time and
amount of data (see attached image) ... I have found not
possible to process with this step whole Landsat8 scene, so
I am doing whole before-mentioned pipeline in cycle
processing 5 rows (1 consists from tiles of the size 128 x
128 px) loosing advantage of artifacts free result.
I believe it can be much faster.
Because of that I am trying to find the way, how to pass
tiled image from PostgreSQL directly to OTB... I have found
http://wiki.orfeo-toolbox.org/index.php/OTB-PostGIS_Interface
but it seems to be focused opposite way: expose PostGIS
functionality to OTB. I would like to expose OTB functionality
(actually only LSMS 4 steps) directly to PostGIS.
Do you know such existing API?
If there is no such API, I would like to contribute to that.
I have experience creating API exposing C++ classes /
functions to PostgreSQL like described in 35.9.13.
Using C++ for Extensibility.

Re: [otb-users] qgis/remote sensing/OTB : needs & expectations ?
Hi,
I use QGis occasionally and I am interested in OTB integration
into QGis. My main expectations are on this integration :
make it as close as possible to standalone OTB applications
with GUI : currently some OTB applications cannot be integrated
as such in QGis. They have to be split in several flavours
because the parameters hierarchy in OTB applications cannot be
reproduced in QGis. For instance there are 3 applications
"EdgeExtraction (gradient)", "EdgeExtraction (sobel)", "EdgeExtraction
(touzi)" instead of a single one in OTB.
make it easy to use latest released OTB applications with an
existing QGis install.

Re: [otb-users] Orthorectification process and No data Pixel
Hi, I also think it is a no-data management issue. The Orthorectification application uses a specific background value when there is no data for the resampled position (for instance, at the corners of the orthorectified image). This background value is set as a no-data flag in the output geotiff. By default this background value is 0 (you can set it with the parameter outputs.default). It could be that some pixels in the shadow regions also have a null value, so they behave as no-data. You can either change the background value, or remove the no-data flag from the output geotiff.

Re: [otb-users] Monteverdi 3.2.0 displays images upside down and doesn't connect to applications
Hi,
Have you used the .bat launcher to run Monteverdi ?
When the image is opened, what is the projection mode displayed by
Monteverdi ? It should be the EPSG code corresponding to your UTM
image.
Regards,
Guillaume

Hello,
I'm new to Monteverdi and to OTB. I have just downloaded
the latest version of the standalone application Monteverdi
3.2.0 (64 bit), for my 64 bit Windows 10 machine. When I load
an image, it is displayed upside down (it's a geotiff with UTM

Also doesn't work. A blank
window shows up.
I would appreciate any advice you might have on getting
Monteverdi to work properly.

Re: [otb-users] matrix multiplication in Band Math?
Hi,
Here is an example where I flip the component order of a 3-band

Where the input context contains both the matrix and the _expression_

#E im1 * kernel1

Re: [otb-users] Moving from CLI to C++

What you're asking is not clear to me :
- the mail title said "moving to C++" but the content is about C
- do you want to have a unique executable doing meanshift

- is it in order to combine other libs with OTB application ? If so,
you may have to use C++

Re: [otb-users] Re: Image tile fusion
Hi, Arthur is right. The number of tile columns and tile rows corresponds to the layout of the tiles you want to fuse.

Re: [otb-users] shoreline extraction
Hi,
I see 2 aspects in your problem :
- the detection of moisture content : you can start with radiometric
indices dedicated to water detection. I am not a specialist so other
people may propose more efficient methods.
- the extraction of the shoreline : this could be done using various
methods : edge detection, segmentation, classification.
For prototyping, using extracts is faster, but with OTB, you should
be able to process full images.

You can check examples here : https://git.orfeo-toolbox.org/otb-data.git/blob/HEAD:/Input/IKONOS_BLOSSEVILLE_ROI_1000_100.geom You will probably have to change the "type" to ossimRpcModel, remove the support_data, and maybe choose a fake sensor name.

Is it possible to integrate some parameter that shows the

By now the only way for me is to check the amount of memory

Re: [otb-users] OTB Applications in Monteverdi 3 Windows 64 Bit
Hi Pieter, In your install folder for Monteverdi3, do you have an executable and a .bat file to launch monteverdi ? You should try the .bat launcher. It adds the necessary environment variable to locate the applications.

[otb-users] OTB 5.2 and Monteverdi 3.0 final release
Dear all, We are happy to announce the release of OTB 5.2 and Monteverdi 3.0 ! This release contains new features for image processing, such as : -> Machine learning : regression support in machine learning models and existing classification filters + two applications dedicated to regression training and prediction, confidence maps for classification. -> SAR imagery : basic support of Sentinel1 products, radiometric calibration updated, new SAR processing (polarimetry, decompositions, conversion of polarimetric matrices to each other) and related new applications. -> A better no-data support : Read, Manage, Write no-data in OTB. -> A richer Python wrapping : Numpy array support, new way of writing an application in Python The remote modules mechanism, introduced in version 5.0, has been a success, with 5 contributions received. Two of them are now official remote modules : -> Generic Region Merging (by Pierre Lassalle) : an application to perform multi-scale region-merging segmentation. -> Images mosaicking (by Rémi Cresson) : a mosaicking application with radiometric harmonization. This release is also the opportunity to introduce Monteverdi 3.0, the successor of Monteverdi2 (but the name has been reset to Monteverdi for more clarity). This version offers : -> a simple stack-layer model : display of several images together. -> the fast rendering of Ice library, with its shaders. All your feedbacks are welcome. If you think you face a bug, you can report it on Mantis : https://bugs.orfeo-toolbox.org You can find the source archives and binaries on Orfeo ToolBox website : https://www.orfeo-toolbox.org/download If you want to explore all the released material : https://www.orfeo-toolbox.org/packages A more detailed description is available on the blog : https://www.orfeo-toolbox.org/blog Best wishes for this end of year !

Re: [otb-users] image conversion (Convert and Rescale)
Hi, What does your input image contain ? Decimal values between 0 and 255 ? For the Convert application, "-type none" means no rescaling, pixel values are just cast to the output type. Could you send the terminal output (for both Convert and Rescale)?

Re: [otb-users] Need help: Superbuild in Mac
Hi, SuperBuild on MacOS can be tricky because some system libs have dependencies that are also part of superbuild. In this case, it is curl that drags CFNetwork. As a first step, try to disable curl (OTB_USE_CURL=OFF).
