Abstract:
A hybrid compression method for compressing images is provided. The method identifies a first set of image components to be compressed by a lossy compression format and a second set of image components to be compressed by a lossless compression format. The method then encodes the first set of image components according to the lossy compression format and encodes the second set of image components according to the lossless compression format. The method then generates a compressed structure that includes the lossy-compressed first set of image components and the lossless-compressed second set of image components.
