Re: [hugin-ptx] "Assertion Failed" on Debian 12 (Hugin 2022)

[Gnome Nomad]

I used to see that in Hugin 2022 on Debian Bookworm whenever I clicked in
an image when manually creating control points. Someone on the list said
that Debian had compiled a lib Hugin used as a debug version.

I haven't encountered it since compiling Hugin 2023.0 RC myself. I don't
know if it was an update to Debian that fixed it, or how I compiled Hugin.

I just followed the instructions on the Hugin page about compiling. I'm no
guru at compiling things so I have no idea what the command line options
listed there do.

Maybe that will help. I'm another person that's allergic to flatpacks.

Re: [hugin-ptx] Compile nona on Amazon Linux

[Gnome Nomad]

Well, if you can figure out how to compile Nona without the rest of Hugin,
it still might not work with Amazon Linux due to some other dependency AL
doesn't include. Good luck!

 Hello,

 I would like to run nona on Amazon Linux, which is a loosely based on
 RHEL.

 I tried compiling the entire *Hugin* release using the following guide
 https://wiki.panotools.org/Hugin_Compiling_Fedora. The farthest I
 could get is running into wxWidget related errors, which is not
 present on Amazon Linux. Compiling it from source fails with even more
 dependencies (some GUI related) which are not available.

 My question would be: Is there a way to compile *nona* only ? I don't
 need any GUI tools.

 Best Regards,
 Pavel Iacovlev

Amazon Linux looks like it's supposed to just be a server, not support
"desktop" oriented tools like Hugin.

Re: [hugin-ptx] Compile nona on Amazon Linux

[Gnome Nomad]

According to this post:

Amazon Linux hasn't really been compatible with RHEL/Centos since 2013.

Re: [hugin-ptx] Hugin - Build for android ndk

[Gnome Nomad]

You sound brave!

Only good point I can see to an Android port of Hugin is it would help
produce a touch screen UI suitable for the touch screen laptops.

I know I couldn't do anything with Hugin on my tablet. Not enough memory or
processor power even for working with my little 6mp images.

Maybe someone with a more powerful tablet would think differently?

Could this "rotate-find verticals-rotate back-change verticals to
horizontals" process be done using Hugin's Python scripting interface?

Can images be rotated in Hugin, find vertical lines be run, then images
rotated back and vertical lines changed back to horizontal?

Or perhaps add a UI option to "toggle selected lines between vertical and
horizontal?

In the panos I do, finding horizontal lines for the horizon (for beach
shots) and church pews (for church interiors) would really speed things up.

First, please refrain from sending images as attachments to mailing
lists. There are plenty of services allowing you to upload images for
free and then just post the link to them.

Secondly, one of the screenshots you posted has the clue for solving
your problems. The error message "Could not find autopano-sift-c.exe in
path" leads me to the assumption that you had installed an earlier
version of Hugin on your PC and when upgrading, did not reset the
preferences.
Autopano-sift-c as a control point detector has been abandoned some time
ago because the licensing for commercial usage was not allowed. However,
if you have installed a version prior to this and not updated your
preferences when upgrading, Hugin still will try to use an application
(autopano-sift-c.exe) for determining control points which is no longer
distributed with Hugin.

So, in order to fix you issues, please go to File -> Preferences and
then to the "Control point detectors" tab. There, you have to press the
button "Load Defaults" which will replace your outdated settings with
the ones that work.

Sorry for not being able to be more precise here, but I do not have
access to a Windows system at the moment.

Re: [hugin-ptx] hugin dev branch: enblend 4.3 too slow

Yes, enblend 4.3 is noticeably slower than 4.1.4. Don't know why. Wouldn't
say so slow as to need downgrading, though.

Re: [hugin-ptx] Re: caught exception: std::bad_alloc with builtin blender

[Gnome Nomad]

Swap space is treated as memory. Temporary files, such as ones created in
/tmp, are NOT memory. They're ordinary disk files. My present laptop has
~420GB of free space, so if something needs to create a 400GB temp file, no
problem!

Linux uses swap space whenever a typical program needs more memory than
what's available. So if Hugin needs more, Linux will use swap space.

I used to use Hugin on a 32-bit Linux system with only 2GB of memory. It
happily used swap space when processing big images. Took a long time - but
it did it.

You don't need to reinstall to enlarge a swap partition. Back up your
system (& home partitions if separate). Boot from a Live linux distro like
Knoppix or Ubuntu. Use Gparted to shrink another partition enough for the
space you want to add to your swap partition. Then enlarge your swap
partition.

Thanks. I think I will do a fresh Linux install with more swap (I need to
do a fresh install anyway).
But are we sure Hugin uses swap files ? If I have an 8GB swap partition and
a 12 GB file, will it work the same as having a 20 GB partition ?

Re: [hugin-ptx] Re: hugin_executor.exe ignores the compression parameter

Oh, I agree that enblend 4.2 should support compression=none since 4.1

it?

This should not be the question. If an option is presented, this option
should be usable.

So, either enblend _can_ and _will_ do uncompressed tif output in this
case, or it should bail out with an error message indicating the reason
why this option is invalid in the current situation.

But just doing something different then the user has requested
definitely is not ok.

Can we have a closer look at this issue? I definitely will do so for the
Ubuntu packages I maintain in the next couple of days.

Re: [hugin-ptx] Re: hugin_executor.exe ignores the compression parameter

[Gnome Nomad]

True, it can use no compression or lossy; one of the benefits of TIFF IMHO.
Only reason I can think of for using no-compression TIFF is when some other
tool in the chain can't handle compressed TIFF. So wondered why OP needed
no compression specifically.

Re: [hugin-ptx] Pretty new at Hugin...can't figure out how to get images into proper order

[Gnome Nomad]

I've done vertical panos of trees featuring a lot of branches. One was on a
fairly windy day, too. I usually shoot for 50% overlap. Hugin did a great
job finding control points.

Re: [hugin-ptx] hugin shouldn't stitch in root.

I don't have /tmp mounted specially - just however Debian set things up.
Perhaps OP tweaked their setup. I can't imagine any Linux distro would ever
point a tmp folder at the root.

Hmm, I've used Hugin on Linux for years now and it has NEVER attempted to
do anything in root. It has always written temp files to /tmp, and remapped
images to the folder containing the pto file.

Re: [hugin-ptx] Stitching untypical photo objects (reflective, people, analog scans)

[Gnome Nomad]

For #2, check out the mask feature. You can use masks to include or exclude
areas of each image. That's basically how you influence the seam line
placement, I think. Do a pano with the car in it and the pedestrian masked
out. Save pano, save pano with a new name, then mask out the car and unmask
the pedestrian.

Don't know anything about the others. You might check the Hugin tutorials
site, wherever it is.

Sorry, I did read it, then had to translate from programmerese. ;)
I have no problems getting control points in 16-bit TIFFs. I've never tried
an EXR as input to Hugin. I sometimes use them as output for use in
Luminance HDR, but that's not dealing with control points.

Re: [hugin-ptx] Level a panorama in batch

[Gnome Nomad]

I've always wondered: rotate each frame 90 degrees and now all the
horizontals are verticles. Run linefind, rotate each frame back, then can
you use a script to turn "vertical" lines into horizontal lines inside the
PTO?

Always thought that rotation was the only conceptual difference between the
two line types.

Thanks, Andreas.

After I did a bunch of hoop-jumping to shift from Sid to testing to fix
some other problems with other packages (none of which depend on
libvigraimpex)? :(

Is the fix mentioned in the bug report showing up in Testing sometime? I
prefer to stick with something more stable than the first Hugin 2016 beta.

Used to use Linux Mint. They're official advice to people wanting to

Re: [hugin-ptx] Hugin 2014 and 2015 "No or only partial information about field of view was found in image file"

[Gnome Nomad]

I sometimes get that. I usually click Cancel, then Hugin just brings them
all in and gets the info correct.

But I usually use pto_gen (Hugin's 'Create PTO from images'?) to create the
PTO file for panos. It always seems to get it right.

Re: [hugin-ptx] Hugin multipe pto generator script

[Gnome Nomad]

Why not just make a subfolder for each pano, move the corresponding images
into each subfolder, then run whatever PTO generator you like on each
subfolder (I use Linux and the right-click tool it already includes)?

Seems easier to me than all the file renaming need for this script.
Especially if you have a lot of images in each pano.

Yes, I had a few complaints about the redesign. None of my complaints were
given any response beyond the above, 'Your issue doesn't cause me any
concern' and boiled down to 'you'll get used to it.'

While I've gotten 'used to it', that doesn't mean they're not issues. I
also find the way of configuring/setting custom exposure adjustments hard
to use. I sincerely hope the present UI is only something 'in progress' to
the real UI.

Re: [hugin-ptx] Verdandi: the new blender

 It is much faster then enblend, just like multiblend is/was.

Re: [hugin-ptx] Assertion error; Hugin 2014.0.0 on Lubuntu 14.04

[Gnome Nomad]

Hmm, I use Debian Sid  get the assertion error from certain dialog boxes
w/ the Audacity audio editor. IIRC, the bug report about that says Debian
compiled some library w/ debug enabled.

I don't get the assertion error in Hugin, I just sometimes get nothing in
the panosphere area except part of whatever is lying behind it on the
screen. Sometimes it shows the panosphere, which is odd because I have it
set to not show the panosphere.

Debian Sid, 64bit, using XFCE  the Light Display Manager, on 3 different
PCs, 2 with Intel hardware, 1 with AMD.

 I always wait at least one year before I download the next version.
Today I went from 2012.0.0 to 2014.0.0 and tried to generate a pano on a
set of Raw images that I had stored in Light Room.  No, I did not try to
use Raw images, I first converted them to TIFFs and moved them to the desk
top.


 What OS, and where did you get your copy of hugin-2014.0.0?



 The first problem I encountered is shown on the following screen shot.
I was not sure what to do so I chose “Cancel”.  BTW, it did not suppress
further warnings, I received the alert several more times.


 I have not seen this before.
 I am guessing that this means you have a hugin built with debugging 'on',
and that there is some problem with WxWidgets.
 Others may know better.

If using Debian Linux, there seems to be some issue between WxWidgets 3 and
Hugin. I just click Don't show this again, followed by Continue, and
everything works.

This is using the Hugin currently available in Debian Sid repository.

 The second problem was that I was forced to manually select the control
points.  I was testing the 2015.0.0 on a set of TIFFs that I had previously
used to create a pano under 2012.0 where I had not encountered any
problems.  It was not a great pano but it ran with no problems.


 Can you elaborate on ...forced to manually select control points?
 Did CPFind not return any control points, or did something else happen?



 The third problem (I gave up at this point) was that when I selected
“Create panorama” I saw the following screen:


 OK, that's expected,


 Followed by:


 This screen suggests that hugin hasn't been able to read the metadata it
needs from your input images, i.e. it doesn't seem to know about the hfov,
which probably affected the finding of control points. At this point you
could enter a hfov= 50 (say) each time you are asked, and see what happens.

Another choice IIRC is to click either OK or Cancel. I forget which.
Happens sometimes when using images from my cheap phone. Hugin proceeds to
bring in the images  give each the correct hfov.

 I would have expected hugin to pop up a dialog box when you first loaded
your images, asking for the hfov, if it wasn't able to figure it from the
image metadata.
 Can you try conversion from RAW to JPEG and pass the JPEGs to hugin and
see if this makes any difference.
 You might also try the Advanced or 'expert interface and see if you
get asked for the hfov for each image when you use Add images.

But he said these were TIFFs that worked fine in Hugin 2012.0.0.

 What happened to the idiot proof interface?

 Probably just trying to proof against a new set of idiots :-)
 Changes to the hugin gui interface were adopted in hugin-2013.0.0 and

 I'd hate to have to store and backup this number of images.

I have only ~48000 images in my collection, they only take up ~500GB. Also,
from what Mike H said earlier, these were cameras mounted outside. Such
cameras might not have very high resolution.

1. Take a lot of photos of the night sky with a fish eye camera.

horrible low-light sensitivity.)
2. Track the brightest 10 stars using some very naive code (that I

3. Run autooptimiser on it and go get a coffee.
4. Run nona on the pano (more coffee)
5. Now you have a stack of 100 photos, all perfectly (?) rotated and
un-distorted that you can sum or do a median filter on, and
6. Get a single beautiful picture of the night sky rivaling those
people with a huge lens and a motorized camera mount.

 I got *public code that works*
 https://github.com/salamanders/virtual-star-tracker, and I think it
 does better than any other method I've seen - and doesn't require perfect
 knowledge of your camera's fisheye distortion.  Anyone want to collaborate
 and help make it less naive?

If that's close, maybe the problem lies in exposure adjustments applied

I get it, too. Even though I don't use JPEG. I use 16-bit TIFF as input

I thought it was fixed in the last 2012 update, but maybe the fix was in 
2013. If I recall correctly, it's only an error message appearing when 
it shouldn't, not an actual error.

I suspect your Android phone has a multicore processor and more powerful 
video hardware. And might also be running in 64-bit mode? This little 
old Sempron processor only has a single core and 128KB of processor 
cache ... Yah, little old laptop!


And Chrome is much faster at Javascript than current Firefox!

I'm also straining the little old laptop's video capabilities, running a 
1920x1080 HD display on a laptop designed for 1024x768 native 
resolution. The video hardware has great difficulty throwing around that 
many pixels since it has to dip into main memory to handle it.

One thing I have noticed while giving a workshop is that different
versions of hugin on different operating systems give different results
on finding control points. On a last workshop I did in June there were
Linuxes, Macs and Windows machines. We tried to put the same hugin
version on all of them and used the same set of images. Some people got
to do the automatic process and others had to set control points manually.

Good idea. I saved the questionable masks, gaussian-blurred them with 64

problems when the original seams were too close to the edge of the image

Instead of something hanging from the lens, you can use something
sticking up from the ground. A branch or stick or whatever you can find
on the scene, provided it is tall enough. Hold the camera just above the
stick without touching it and shoot as needed.

It's easy to stick something in the ground if you shoot on grass or
soil. In the asphalt jungle that won't work so I leave it to the reader
to be creative... I once used a piece of rebar sticking up in the ruins
of a half-demolished building I wanted to capture close-up.

I use the standard complete Hugin.. for win x7 and it cant deal with

it can do it with the 14mp pics from my fuji..

i went to 20mp because i thought the image control points the assistant
uses, would work better with better definition... but in effect ive
limited how many pics i can use..

so i see , Fred that my problem isnt limited to me..


Hmmm, could you put like 6 of your problem pix online somewhere? I have 
32-bit and 64-bit Hugin on Linux here, would like to see what happens. 
I'm thinking about jumping to a 24mp Nikon DSLR when my current 6mp 
Maxxum 7D finally dies.


I did find by experiment one time with my 6mp images that running cpfind 
with the --fullscale option that processes each image at full scale 
required just about 2GB of memory. So how much memory would a 20mp image 
need for similar processing? Not that you're necessarily processing your 
images at fullscale ...

problem, and I regularly blend up to 60 images.  With only 8 GB this

  enblend: cannot load image 20120702-125206-125507-09.tif

This looks to me like this specific file is corrupt, though that
doesn't fit what the remainder of the report.  I occasionally end up
with empty input files which trigger this kind of message.


The images are not corrupt, I do the partial panos from a shell script
taking the files which leaves nona.


What kind of blending are you doing?  Are you doing it from the
stitcher tab or from the Makefile?


Tried both ways.


Can you reduce the size of the images and still reproduce the problem?
If so, I could take a look.  If not, how big are the images?

The originals are 2000x3000 16bit tifs. For the pano, I'm doing at the
moment,
the intermediate files (nona output) have file sizes of 20-60 Mbytes.
This problem arises with all panos with more than 9 images I have done.
Also tried a different computer with similar setup at work, same result.
Have changed TMPDIR pointing to a disk with plenty free disk space (250G).


Very odd. I've stitched panos using more than 40 2Kx3K 16-bit TIFs, from 
Hugin, on 32-bit Linux (Debian Sid) with only 2GB RAM, without any 
problems beyond it taking about 6 hours (1.5GHz Celeron M, single-core 
processor). Even generated a 784MB 16-bit TIFF image once, but I don't 
remember how many 2Kx3K frames were in that one.


Not helpful, I know, other than it makes me wonder if the difference is 
Linux vs FreeBSD.

  So yesterday I asked myself: Is it possible to figure out the
camera-intern control parameters for lens correction with
out-of-the-box-JPGs?
  The Idea is to shot for each focal length ONE photo and let it save
by the camera as RAW and (lens-corrected) JPG. Then process the RAW
image without any distortion-correction.
  After that, the big question: Can Hugin stack these two images
about each other, so that the uncorrected image is deformed (with
the needed correction parameters) on top of the other?

Yes this will definitely work: just load both photos and make sure
they have different lens 'numbers'; set lots of control-points; then
optimise a,b,c,d,e,v for the distorted photo only.

This stacking technique should be foolproof, though I would still
expect to get better results using the standard Hugin technique of
stitching partially overlapping photos.


Why not just make a pano from RAW images, using lots of overlapping
CP's, and let the good ol'
optimiser both assemble the pano, AND calibrate your lens at the same time?

That's what I did with my new (Panasonic TZ8) camera when I first got it.


That's what I've always done. Never bothered to calibrate my lens(es) 
because they're all zoom lenses, so I suspect distortion changes as zoom 
changes, perhaps also as aperture changes.


I've not shot both RAW and JPG. I'd be really surprised if in-camera 
processing can do any correction for lens distortion. Does the camera 
contain a full database of the possible lenses you could put on the 
camera (I use a DSLR)? If it does any kind of software distortion 
correction in camera, I can't imagine how it could do anymore correction 
than Hugin does, and quite possibly doesn't do it as well.


Maybe new cameras are fancier now, but I'm highly doubtful that any of 
them can do any correction for lens distortion. Of course, probably 
someone knows different. Or some camera makers marketing departments are 
run by lunatics ...

My (getting elderly now) lumix lx3 pocket camera does barrel distortion
correction in-camera for JPEG files. I've never tried comparing it to
RAW output, and clearly this approach wouldn't work for cameras that
take generic lenses.


Apparently some Nikon DSLRs can do it, but only with Nikkor lenses:

http://www.dpreview.com/forums/post/50461788

The process sacrifices some sharpness, crops the image somewhat, and 
doesn't necessarily do as good a job as outside-the-camera software 
processing does.


I'd rather keep the sharpness and full image and do corrections outside 
the camera. But I never shoot JPG, just RAW.

or a workaround. There are many more eyes on this list than Lanchpad.

Re: [hugin-ptx] bug linefind and edge of image

[Gnome Nomad]

I mentioned it and you addressed the apparent fact that we were getting 
essentially TWO footers on each message ... thanks.


A link to LaunchPad might make bug reporting easier for anyone interested.

Hi,

I somehow remember that you complained about the length of this mailing
list's footer (being the one who adds a much longer own footer to every
one liner).

The Hugin FAQ mentioned in each message has some hints about bug
reporting, I'll add a direct link to launchpad now for your convenience.

This is intentional.  Cpclean will currently only remove normal cp.
All line control points are ignored (also for calculation of errors/limits).
The background was, that line control points are often set manual to
correct perspective or to level a pano. In my experience they have often
a little higher error than normal cp. So I ignored them in cpclean.
But I'm open for improvement proposals.


Question: I don't know how cpclean works. Does it take into account the 
existence of line CPs when evaluating a normal CP? Such as if I have a 
vertical line with one of its CPs located close by a normal CP?

I know that currently GIMP is still limited to 8 bits / channel. I only
meant that GIMP does not complain about the bit depth when loading a
48-bits image. Actually, I have looked everywhere for a mention of the
bit depth in Gimp but have been unable to find any. Gimp is very quiet
about this :-)


GIMP has stated that GIMP 3 will have full 48-bit color support, 
including for all effects, filters, etc.


Photoshop has had 48-bit support for a long time now, since 48-bit color 
is the professional photography standard.


The problem with transparency and digital photographs has been around a 
long time. When JPG standard was defined, it didn't include 
transparency. I think it's because the joint photographic experts take 
transparency to mean a type of film image, not an attribute of a 
photograph. ;-)

thanks for the suggestion!  I had tried that, too, but it didn't help.

But I finally found the reason:  The update had overwritten the libglx.so from

So after re-installing the NVidia driver things work again.

Re: [hugin-ptx] Hugin crashes after system update (x server?)

   Hello list,

I am running a self-compiled hugin version from mercurial (current version:
20e34581ca6a), and use it a lot for panos and aligning stacks.

Two days ago I did an update of my system (openSUSE 12.1 with KDE SC 4.9), and
since that update hugin is crashing when I try to start it:

   The program 'hugin' received an X Window System error.
   This probably reflects a bug in the program.
   The error was 'BadWindow (invalid Window parameter)'.
 (Details: serial 1971 error_code 3 request_code 137 minor_code 4)
 (Note to programmers: normally, X errors are reported asynchronously;
  that is, you will receive the error a while after causing it.
  To debug your program, run it with the --sync command line
  option to change this behavior. You can then get a meaningful
  backtrace from your debugger if you break on the gdk_x_error() function.)

The update wasn't large, the only thing that seemed related was a minor update
of the xorg-x11-server (7.6_1.10.4-36.5.1- 7.6_1.10.4-36.9.2) claiming to fix
only some console switching issue.

My first try was to recompile hugin, but that didn't help.  So I decided o
revert to the old version of the X server.  But hugin still crashes!  I tried
to follow the suggested 'sync' option and run it in gdb, but a backtrace only
gives a 'No stack'.  That's where my skills end.

I had a closer look at the list of updates, but cannot really see what might
be the reason for the change.  Does any of the Developers here have a hint
what I should be looking for?

Here's a list of packages that did get updated:

FreeCAD libphonon4 phonon-devel mkinitrd java-1_6_0-openjdk libtiff3 libcurl4
xorg-x11-server xorg-x11-Xvnc libcurl4-32bit libgnutls28 libtiff3-32bit
libtalloc2 libwbclient0-32bit libtdb1-32bit libtdb1 libtalloc2-32bit
libwbclient0 libtiff-devel libcurl-devel flash-player curl libgnutls-devel
libtevent0 libsmbclient0 flash-player-kde4 libldb1 libgphoto2-6 rawtherapee
darktable libgphoto2-6-lang photivo photivo-gimp libmpg123-0 mpg123 MPlayer
gmplayer wxcam handbrake-cli xine-ui libopencv2_4 opencv opencv-devel
plus a bunch of gambas3 packages

Thanks,

   Pit

Yes, it has. Either select the High dynamic range output, which

Exposure fused output, which uses enfuse.


Thanks, that's right. I've done it both ways with no problems on Linux.

I think the original poster's problem was crashes when trying to output

could be exceeding the memory capabilities of 32-bits?



According to my estimates, cpfind with default setting was going to take
~1 months of computation (4 core i7-3820, 32Gb ram). It was not in a
swap - it consumed ~26Gb of ram, without excessive swapping.
After setting cpfind to only match 50 consecutive images (instead of
everything) it sucesfully finished in 2.5 days, but he found 7
unconnected groups - and I simply had no idea how to fix it given that
UI was extremely non-responsive (literally every click in UI was
freezing Hugin for ~5-10 seconds). Obviously trying different parameters
and waiting 2.5 days for each try is unrealistic...

Any suggestions on how should I attack this problem?
I am likely to need to repeat this panorama shooting  stitching 3 more
times, and I already feel the pain.

Currently I am trying to stitch reduced images (0.1mpix instead of
5mpix), and then save the project, update coordinates inside the project
file, replace images by larger ones, redo control points (cpfind
prealigned), and hopefully it would work - but smaller images seems
harder to stitch (as number of images is the same, but many details
vanishes).

Re: [hugin-ptx] Hugin crashes exporting EXR hdr files

[Gnome Nomad]

Hmm, I shoot 16-bit/channel RAW files (both for HDR and non-HDR stuff). 
Process them into similarly 16-bit/channel TIFFs that I then stitch 
and/or align using Hugin. At the end of the process, I have 
16-bit/channel TIFFs. No values being clamped to 8-bit anywhere in the 
chain or the final output. Puzzled where you get that idea ...


I used to do the image swap trick you mention in 1 (below), when Hugin's 
vertical line fine was unable to function on 16-bit/channel TIFFs. I'd 
generate a set of 16-bit TIFFs, then generate a set of 8-bit TIFFs in a 
separate folder. Then I'd use the 8-bit TIFFs to create and finalize the 
Hugin project. Then I'd copy the resulting PTO file into the folder with 
the 16-bit TIFFs, and either stitch it, or reoptimize exposure and then 
stitch.


I do believe Hugin has a way to merge different exposures into a single 
image. I've done it but don't presently recall how.

Ouch, I meant what was the point of having 16bits when values were being

I will have another go at it, I have some feedback on it but not sure
where to post it so I'll stick it in here, I can create a separate
thread if needed.

1 - It would be great to be able to swap images or specify proxies,
imagine the following scenario, you have a some huge HDR images that you
want to stitch together, ideally one would resize them to a different
size or to some 8bit format, say jpeg to make working with them faster,
then swap them when you're about to stitch the panorama.

2 - Hugin doesn't seem to have a way to merge different exposures into
one image? This would definitely help a lot of vfx people to turn to
Hugin rather than relying on propietary tools, probably getting some
donations from small studios to help out with the project?

This must be a library error as I don't see it on Linux.

  Exporting 16bit tiffs is still an option, but they seem to be
clamped to 1, so I am not entirely sure what is the point of having
8bits if every value is going to be clamped to 255 anyway.

The TIFF output when you feed it HDR input is actually full HDR
32bit float. So until EXR is fixed you should be able use TIFF instead.

Re: [hugin-ptx] Bad panorama after optimizing control points

Suggestion: before optimizing control points, run Clean Control Points

way you describe before.

First there is not enough space for the spinner and the explanation
text.
Second cpfind is the Hugins default control detector. It does not
support this parameter directly.


Really? OK. I've been specifying the number of control points per 
overlap for a long while using the 2012 version, and using Hugin's 
cpfind ...



So hold down the control key when pressing create control points.
Then you can specify the number of control points per overlap.


Really? Cool. Thanks.

Talk about hiding a feature in a completely unintuitive way ... I'd 
expect such a feature to be hidden in the Simple interface, but visibly 
obvious in the Expert and Advanced modes ...

On 03/26/2013 07:12 AM, T. Modes wrote:


Is this intended behavior?



Yes. In advanced and expert mode the window behaviour has not changed.
It is the same as in the last versions.

The main window is the panorama editor. Here you can open/save/create
new projects.
You can open the fast preview window. It is opened automatically if
Hugin was closed with open (and not maximized) fast preview window.

If you close the fast preview window (the secondary window) only this
window is closed.
If you close the panorama editor (the main window) the application is
exited.

In simple mode main and secondary window are exchanged, but the
behaviour remains in the same style:

The main window is the fast preview window. Here you can open/save
projects.
You can open the panorama editor.

If you close the panorama editor (the secondary window) only this
window is closed.
If you close the fast preview window (the main window) the application
is exited.

So the behaviour is consistent, but require some familiarization for
old users.


Unnecessarily confusing, both for new and old users, IMHO.

Your image shows the top of a window I see here as the main editor, and
on top of that, what appears to be the preview window.
In other than the simple interface, you would normally use the editor
window to load images, get your control points etc.
Using the simple interface you would only see the preview window and
you can use the assistant tab to load images, align and stitch.
The editor window (in other than simple interface) provides the access
to detailed operations.
You should be be able to close the preview window (the one with
assistant) and work in the editor window pretty much as you would have
in previous versions of Hugin.
Sorry if I haven't correctly understood what you are saying.

[hugin-ptx] Trying to install Hugin 2013.0.0-beta1 from Debian Experimental repository

[Gnome Nomad]

Enblend, enfuse, hugin-data packages accept the force version in 
Synaptic. Forcing the version on Hugin package says that hugin-tools 
will be removed. Forcing the version on hugin-tools says that Hugin will 
be removed.


By clearing all the markings and then selecting upgrade for all of them, 
I got it to show Upgrade for all of them.


It then informed me that Luminance HDR would be removed! I cleared that 
mark. Luminance HDR 2.3.0-3 depends on hugin-tools for align_image_stack.


Attempting to update to 2013 Hugin beta1 was then unable to proceed, 
reporting:


E: Unable to correct dependencies
E: Error, pkgProblemResolver::Resolve generated breaks, this may be 
caused by held packages.


I'm running Debian Sid.

Tried apt-get clean and autoclean, tried reloading, still does the same 
thing.


So it looks like I can't test beta1, since I need Luminance HDR around.

Not this user. Please, don't resize my Hugin window without asking.
Perhaps there could be a toggle to enable/disable this, if implemented?


I wouldn't expect it to resize my Hugin window, either. I've never used 
a graphics program that did that, either. I think most automatically 
resize the *image* to fit into the window the program is putting it in.


Perhaps a quick keystroke to resize window to fit image would be 
useful to some?

Re: [hugin-ptx] Google Summer of Code 2013

Like a control dowel would be a line (defined as straight) that 
connects single points between multiple separate frames? An any angle 
generalization of a horizontal line spanning multiple frames?


My understanding of horizontal lines is probably flawed ...

Hugin and Panotools community,
What new ideas do you have that a student could implement?



I'm the type to make panos while holding my p-n-s Canon S95.  I've tried doing 
some bracketed shots and create HDR from that, but I've had limited success.  
Mainly due to hand movement and images in one stack overlapping another stack 
too much.  Understandable, really.

But the thought occurred to me that maybe instead of control points, what we really need 
are control dowels - sort of like forensic police dowels used to plot the 
trajectory of a bullet**.  I would think it would allow connecting different exposure 
levels of the pano together easily, as well as through each stack? Maybe a little 
ambitious?  I don't know of any other software using that type of system, so it might be 
a good opportunity at breaking new ground for some aspiring student.

I freely admit that I'm not sure the ROI on this would justify the effort.  
Just throwing it out there.

So somebody on Ubuntu should have a look on this issue.


Wouldn't surprise me. My wife and I both use the same mature, very

The Unity UI has joined my short list of software I always replace on

I don't know what monitor you are using. I have no monitor which would
support resolutions to show typical panoramas in 100 % ;-) The pano
canvas is always downscaled.

It was just an echo of the idea the original poster seemed to think - 
that graphics programs automatically size their window to hold whatever 
image you open in the window. I've never met a graphics app that did 
that, but I've not met them all ...  Clearly, such a toggle should come 
with the ability to recognize the max window size (display resolution or 
largest canvas area available, whatever) and make the window that large 
but no larger (like when you maximize the window). If it was going to 
work like a graphics app would probably handle it, if the chosen image 
scale gave you an image larger than that window, it could provide scroll 
bars or a scroll box like GIMP does to facilitate moving around in large 
images. But there'd have to be a balance somewhere to keep the program 
from trying to display a 100% sized gigapixel panorama ... ;-)

So to turn Darwin into OS X, we only need to add a number of other 
items, particularly key Apple-proprietary (non-OSS) pieces. Sounds like 
OS X is proprietary, to me - not OSS. It may have a slab of Darwin OSS 
beneath it, but OS X is not Darwin. So OS X is no longer OSS. Doesn't 
sound strange to me at all!


Anyway, I've used OS X (and Windows and OS/2 and Linux), too. Glad you

I did. I never said OS X was never OSS. I said it had moved so far 
beyond its OSS foundation (Darwin) that in my opinion it's no longer 
OSS. I don't have to add a particular manufacturer's closed-source 
proprietary code to Linux to make it Linux. So OS X does not stand on 
the shoulders of OSS the same way Linux does. In a strict 
interpretation of some OSS licenses, some might say that *OS X would be 
in violation of those licenses*.


But this isn't making Hugin any better, regardless of platform it 
happens to run on. Now Hugin on a Google Nexus 10 - that would be 
interesting!

LZW doesn't compress 16 bit very good. In fact I found LZW
compressed 16 bit TIFFs larger than the uncompressed version most of
the time.


Hmm, have never had LZW compress a 16-bit TIFF and make it LARGER than 
the uncompressed version.


Just tested here with single-layer TIFFs converted from 48-bit RAW files 
(6MP image):


8-bit TIFF: 17.2 MB (uncompressed) = 6.1 MB (LZW)
16-bit TIFF: 34.4 MB (uncompressed) = 30.7 MB (LZW)
8-bit JPG: 4 MB

LZW compresses both TIFFs to less than the original size.

Just for grins, same results using ImageMagick's ZIP compression option:

ZIP compressed 8-bit TIFF: 5.7 MB
ZIP compressed 16-bit TIFF: 25.5 MB


And DevalVR standalone (which is my favorite spherical
viewer) doesn't show LZW compressed TIFFs...


Sounds like a feature they should add. But TIFFs aren't used much for 
image display on the web, because they're too large.



I just did a test with a jpg original, it lost 50% size with compressed
tiff besides uncompressed tiff. But maybe a jpeg image lends itself well
to compression.


JPEG compresses by *throwing out parts of the image* like MP3 and other 
audio formats. It is a LOSSY compression method. What they throw out is 
determined by psycho-perceptual studies that showed, We can throw this 
out because the average human eye/ear doesn't really perceive them very 
well. TIFF doesn't lose any parts of the image.


When you uncompress a TIFF, you get back the exact image you compressed.

When you uncompress a JPEG, you get back something that looks like the 
uncompressed image, but isn't an exact match.
