For the lossless compressionof an RGB image, it is first decorrelated by a reversible color transform and then Ycomponent is encoded by a conventional lossless grayscale image compression method.For encoding the chrominance images, we develop a hierarchical scheme that enables theuse of upper, left, and lower pixels for the pixel prediction, whereas the conventional rasterscan prediction methods use upper and left pixels. An appropriate context model for theprediction error is also defined and the arithmetic coding is applied to the error signalcorresponding to each context. For several sets of images, it is shown that the proposedmethod further reduces the bit rates compared with JPEG2000 and JPEG-XR.Existing systemThis paper presents a new lossless color image compression algorithm, based on thehierarchical prediction and context-adaptive arithmetic coding.
