This paper proposes a decision region adaptive MPEG 2 quantization algorithm.
提出一种MPEG2量化器的区域自适应率失真优化算法。
The source distribution in decision region of quantizer is considered in this algorithm, and the decision level of quantizer is derived from the procedure of searching the minimum R D Lagrangian cost.
这种算法考虑了信源在量化器量化判决区域的分布，通过寻找最小的拉格朗日率失真费用函数，获得量化器的判决电平。
