摘要 |
Predictive lossless coding provides effective lossless image compression of both photographic and graphics content in image and video media. Predictive lossless coding can operate on a macroblock basis for compatibility with existing image and video codecs. Predictive lossless coding chooses and applies one of multiple available differential pulse-code modulation (DPCM) modes to individual macro-blocks to produce DPCM residuals having a closer to optimal distribution for run-length, Golomb Rice RLGR entropy encoding. This permits effective lossless entropy encoding despite the differing characteristics of photographic and graphics image content. <IMAGE> |
