We propose a new lossless progressive color coding of color still images. An image is firstly transformed by reversible Wavelet 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 suhbands of reversible wavelet transform. We show three effective predictors to remove that correlations, and it is confirmed by nnmerical experiment that combination of all the predictions is the best in performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
