Hi,
I have a NITF file which contains JPEG2000 imagery. When attempting to read the image via "nitfread()" I receive an error regarding it not supporting compressed imagery (subheader compression type of 'C8').
I do see that "imread()" supports JPEG2000 files, however, so I'm curious if anyone has a workaround for this issue? Any plans on adding direct support for this in an upcoming release?
I'm running w/ MATLAB R2011b / Image Processing Toolbox 7.3.
Thanks in advance for any advice or suggestions.

Only MathWorks Sales (and very high management) are authorized to speak about what will or will not be supported and in what timeframe.
I am not familiar with NITF files or how much work would be required to deal with compressed JPEG2000 files.

Try:

Given a filename, it will produce a JP2 tempfile in the current directory.
It may require some adjustment depending on the contents of the file and how you want to handle the output, but I don't have any files to test.
