strange behaviour of opj_jp3d_compress/decompress utility

[franfcunha]

Hi,

I am trying to encode and decode a binary volume using JPEG2000 Part 10 framework.

I can successfully call the respective enc/dec executables. However, I am unable to get a meaningful reconstruction of the compressed bitstream. Furthermore, after encoding in lossless mode (default) and adding -O and -m options once decompressing in order to compare the original (uncompressed) volume and the decoded one, PSNR equals 'nan' and SSIM a value close to 0.02.

What can be happening then? Any idea? I've played with byte-order of the input stream and no matter what I provide to the encoder, the respective reconstruction after decoding is always leading to loss of information even though in lossless mode!
