Noise image compression

问题:

I have "noise" image... what is the best way to compress this image ? It can be little lossy. Techniques based on DCT and Wavelet are bad for this sort of problem. My idea was to generate some recreatable noise and then store only differences... but I cant find any solution for recreatable noise images.

Well, it's almost the definition of noise to not be compressible.

This statement applies to "real noise", when there is no known correlation between the perceived output and another applicable rule. So if your image is just that, or built to look like it is, then sorry, it's not compressible.
