失真度

• The visual quality of decoded video information is improved at some extent and psnr value of luminance parts is increased nearly 1 db in error - prone channel . 4 . an adaptively rd - optimal coding algorithm was proposed to be aimed at the computing redundancy in h . 264 recommendation algorithm
  针对h . 264标准率失真优化编码算法中存在的计算冗余过大问题，提出了一种自适应率失真优化编码算法，将h . 264标准算法中求解解码重构视频信息期望失真度的代数和平均算法，改进为加权和平均算法。
