6,运动矢量和量化表的分解与合成 :广义小波 ;
7,位面编码 :数学形态小波,多级树集合群,嵌入零树,位面降维 ;
8,位流编码 :算术编码,熵编码 ;
9,运动估计 :宏块最优决策,运动矢量预测 ;
A,运动搜索 :钻石,大钻石,小钻石,方形 ;
B,图象与声音后处理 :低通滤波,断点重构,宏块平滑 ;
C,误码纠错 :矢量仿真,帧间仿真 。
(The PAV (H265) is the audio and video compression and decompression protocol, is very different from H264/MPEG4
ZPAV (H265) algorithm is a wavelet, multi-level tree collection group, and generalized wavelets, mathematical morphology, wavelet, ...
ZPAV (H265) algorithm:
1, image and sound decomposition and synthesis: wavelet
2, image and sound processing: wavelet sub-band zero-crossing noise, target texture processing, speech processing
3, the rate control: wavelet subband entropy rate control
4, quantization and inverse quantization: Wavelet subband entropy quantization and inverse quantization
5, the dimensionality reduction of the low frequency component and high frequency components: the wavelet subbands neighborhood cross-dimensionality reduction
6, the decomposition and synthesis of the motion vector and quantization tables: generalized wavelet
7, bit-plane coding: the mathematical form of wavelet multi-level tree collection group, embedded zerotree, bit plane)
