New simple and efficient color space transformations for lossless image compression
New transformation requiring 4 operations per pixel gave the best overall ratios. New transformation done in 2 operations gave the best JPEG2000 and JPEG XR ratios. A transformation from human vision system outperformed established ones. PCA/KLT resulted in ratios inferior to ratios of new and established transformations.
