lzari压缩算法
这是一个基于LZARI算法的数据压缩的类.Haruhiko Okumura 于1989年7月4日用C语言写实现了这个算法.但是上面用到了一些全局或静态的变量,在MFC下用起来很不方便.作者把它改写成了一个C++类,使它可以方便的压缩和解压缩。(LZARI algorithm based on the type of data compression. Haruhiko SAP in 1989, July 4 C language daily wrote realization of this algorithm. But above uses some static or global variables, using the MFC which are very convenient. Authors rewrite it became a category C, it can be to facilitate the compression.)

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)
