查询词典 precision

After a brief review about the problems of bit rate control for MPEG video coding, two optimizations are proposed based on MPEG-2 Test Model 5 (TM5) algorithm:①An intelligent integral action is introduced for improving the control precision of bit rate;②After using DCT AC coefficients to define the measure of macroblock and picture coding difficulty, an improvement on target bits allocation is proposed for the decoded picture quality and conformance including scene change, which can ajust the target bits allocation adaptively by their measure.

文中首先对MPEG视频编码比特速率的控制问题作了简要回顾，然后针对MPEG-2测试模型5(TM5)算法进行了以下优化：①引入一种智能积分作用，有利于提高比特速率的控制精度；②采用DCT交流系数定义宏块和图象的编码难度测度，然后提出了优化的目标编码量分配策略，即根据编码难度测度自适应调整图象和宏块的目标编码量，这样有利于提高包括场景变化在内的图象解码质量及其一致性。
