Re: Correct implementation of RGB channel decorrelation


Probably. What are your objectives? Lossy? Lossless?

Lossless

What's the problem with YCbCr? Or probably with the RCT in
JPEG2000, if you need a reversible transform?

I need channel decorrelation as first step of an image compression algorithm
to help improve compression.
I need a color decorrelation step wich is fast, lossless and easy to
implement. Also patent free.

Thanks
