[OSGeo-Discuss] OS Spatial environment 'sizing' + Image Management

[Traian Stanev]

JPEG2K supports lossless via a reversible wavelet transform with integral coefficients (which make it reversible, and so lossless). Here is a reference:

Thanks for the comments Michael,

I was wondering if you'd contribute    ;-)

Can you point me to any studies to support the claim that JPEG2000 can indeed be indeed non-lossy?


I've seen the claims over the years, but nothing to support it (not that I've actively gone looking for the info, as I haven't had the need).
