To extend willvarfar's question, can you shift color channels in a reversible way so as to get compression. Compare the two process. 1. raw_image -> image_compress(raw_image) 2. raw_image -> shift_color_channels(raw_image) -> image_compress(shift_color_channels(raw_image)) * Thinking out aloud * Is the 2nd process feasible? Is it possible that the current image compression algorithms pick up on the aberration patterns which invalidates the need for the 2nd process? In the case of image compression using wavelet transforms (which many methods use) and if wavelets can pick-up on the aberration patterns, could the hurdle be finding a finite set of wavelet functions that can work for majority of the lenses?
