Abstract
A comparison of lossless compression results is given for RGB, YC/sub R/C/sub B/ and reversible JPEG 2000 color space. The paper describes the general conditions that rounding errors of a color transformation do not cumulate in the consecutive cycles of forward and inverse transformation. In particular, rounding errors of the RGB/spl rarr/YC/sub R/C/sub B//spl rarr/RGB transformation do not accumulate in the consecutive transformation cycles. Luminance and chrominance representation with two additional bits leads to perfectly reversible color transformation. For such representation, compression is slightly better than in RGB but worse than in JPEG 2000 reversible color space. The paper comprises a study on the accumulation of errors produced by near-lossless JPEG-LS in the consecutive compression-decompression cycles. The paper proves that, alternatively, lossless compression can be performed on luminance and chrominance with reduced representation bit numbers. The advantage is that the errors do not accumulate in the consecutive cycles of compression.
