Thanks, Remi. That's what I imagined. In fact, I processed them using two
subsets and using two threads but the results were not satisfactory. Your
splitting strategy makes much more sense of course.

Hello Gus,
The logs help, thanks.
The application crashes when the statistics are summarized, because there
is not enough memory to store the mutual statistics for your 3582 images.
In short, the mutual statistics between couple of images (i,j) are stored
in matrices of size NxN (N = 3582
Sorry about the delay. I used gdal_translate as you told and some gdalinfo

running the no harmonization pipeline and next one tomorrow. In case it
fails, I will try again with a clean installation (half my hd is full of
Hello Gus,
I don't think so because the entire process is streamable.
It's difficult for me to help you without the full log. Can you run on
linux the following commands:
otbcli_Mosaic -il /media/gus/Gus/seagrass/3_band/* -out
/media/gus/Gus/seagrass/processed_data/r2_simple_noharmo.tif uint8
No, it didn't, but I separated two sets, one for each flight, and one of
them did ran (I still didn't try the other). May it be related to some
convergence during optimization process?

No. The application computes the distance map for each input image, one by
one. Not for the entire mosaic.
Did the change of image file format solve your issue?

When you say that "Meaning that, for each input image to mosaic, the
distance map will theoretically require the full image in memory to be
processed." do you mean that, for every single input image, I need to load
an array with the full size of the output mosaic?

Your GeoTiff is compressed (PACKBITS) and has rectangular blocks of
416x320. This problem could come from here has you have 2.5k images.
I would give a try to unflate all your images. To do it, use gdal_translate
-of "GTiff" -ot "Byte" input.tif output.tif
then re-run Mosaic !

The color space is l-alpha-beta but I don't think it's related to this
strange behavior.
I suspect that your images are in a non-streamable format. Meaning, you
can't read them block by block, instead you are forced to read the entire
file. Can you paste a gdalinfo of 1 of your file (feel free

To be sure of this, can you please check that the following commands work
fine:
- otbcli_Mosaic -il /media/gus/Gus/seagrass/3_band/* -out
/media/gus/Gus/seagrass/processed_data/r2_simple_noharmo.tif uint8
I tried again last night. OTB 6.6.0 packaged linux version.
Command line: ./otbcli_Mosaic -il /media/gus/Gus/seagrass/3_band/*
-comp.feather large -harmo.method rgb -harmo.cost musig -out
/media/gus/Gus/seagrass/processed_data/r2.tif uint8 -tmpdir

64-bit windows orfeo toolbox 6.6.0. I launched it from GUI, not from
command line. I will try tomorrow again and save a log, although I was
thinking on trying to compile in linux.

Hello Gus,
To investigate a bit I would like to know if you can copy/paste:
-your command line
-the full log
(In a text file, or on pastebin)
What version of OTB, and what OS do you have?
Thanks,
Rémi

Hello Gus,
The RAM parameter deals only with the memory footprint during mosaic
compositing and statistics computation, both streamable pipelines (no
limitation on images size).
However, the distance map calculation (which is a temporary file, then used
as an input of the streamed mosaicing
