Create Floating Point JPEG2000

Processing
1

Hi

I have some scientific images with non-gamma transfer functions and would like to convert them to floating point JPEG2000 for display.

I’ve looked at various tools and libraries but can’t seem to find one that allows me to write floating point images. I would like to set the diffuse White Point to 1.0, allow specular highlights above that level etc.

Does anyone know of a tool that can do this?

It depends on the input and your intended encoding scheme.

A lossless jp2 is encoded in integer mode=int (biorthogonal Cohen–Daubechies–Feauveau 5/3 wavelet transform)
A lossy-compressed jp2 can have mode=real (CDF 9/7 wavelets)

Have you tried geojasper’s tools? http://www.dimin.net/software/geojasper/
