Inter Color and Inter Intra Band Prediction on Reversible Wavelet for Lossless Progressive Color Coding

We propose a new lossless progressive color coding of color still images. An image is rstly transformed by reversibleWavelet transform such as S transform due to progressive transmission of image. And we utilize for an improvement of the compression performance not only the inter color correlation but also the inter/intra band correlation of the subbands of reversible wavelet transform. We show three e ective predictors to remove that correlations, and it is con rmed by numerical experiment that combination of all the predictions is the best in performance.
