I am looking the support for Jpeg_LS from IPP library. However I have find any IPP function do JPEG-LS. Does Intel have any plan to support JPEG-LS in IPP?
I aslo hope to speed up Rice-Golomb coding process in a puiblic JPEG-LS code. Does IPP has any function can do fast Rice-Golomb encoding?

currently we only support JPEG lossless mode. We do not have JPEG-LS specific functions in IPP. Do you have any certain performance requirements for that functionality?
Note, you may submit your feature request to Intel Premier Support channel.
The JPEG-LS is very good for medical image lossless compression. We found it's lossless compression ratio is best among lossless JPEG, lossless JPEG-2000, and other compression. The JPEG-LS algorithm is very simple too. We hope it compression speed is as fast as IPP-JPEG.
However the test for public domain code shows the process slow down on entropy code stage using Rice Golomb coding.
