基于改进K

huffman编码译码器，实现前提是消息中的字符及其频度均为已知量！-huffman

鉴于网上公布的x264调用较为复杂，使很多新手不适，我特意将其进行了简单的封装，并提供了 lib 和 测试程序，该程序已经通过编译，修改 宽高及文件路径等即可运行-In view of online publication called the x264 is more complicated, does not make a lot of novice, I made it for a simple package, and provides a lib and test procedures, the procedures have been adopted by the compiler, modify the path wide and so high and documents can be run

ZPAV (H.265) is audio-visual codec protocol, very different from H264/MPEG4, ZPAV (H.265) basic algorithm is wavelets, SPIHT, BSW, MMW, ...... ZPAV (H.265) basic algorithm : 1, analysis/synthesis : wavelets 2, denoise : GCV (generalized cross validation) 3, bit-rate controller : entropic bit-rate controller 4, quantizer : entropic quantizer 5, DC/AC : NDLD (near-domain lower dimension) 6, MV/QP codec : BSW (generalized (broad-sense) wavelets) 7, bitplanes codec : SPIHT, EZW, MMW (mathematical morphological wavelets), BPLD (bitplanes lower dimension) 8, bitstreams codec : arithmetic, entropy 9, motion estimate : MBOD (macro block optimal decision), MVP (motion vector prediction) A, motion search : EPZS, diamond(normal, advance, small), square B, post process : low_pass, default, dering filter .

算术编码方法是将被编码的一则消息或符号串（序列）表示成0和1之间的一个间隔（Interval），即对一串符号直接编码成[0,1]区间上的一个浮点小数。符号序列越长，编码表示它的间隔越小，表示这一间隔所需的位数就越多。信源中的符号序列仍然要根据某种模式生成概率的大小来减少间隔。可能出现的符号概率要比不太可能出现的符号减少范围小，因此，只正加较少的比特位。-Arithmetic coding method is to be a coded message or symbol strings (sequences) that between 0 and 1 into an interval (Interval), that is directly encoded into a string of symbols [0,1] range of a floating-point decimal. The longer the symbol sequence, encoding the smaller the interval that it said that the median of this interval, the more necessary. Source is still the symbolic sequence generated according to a mode to reduce the size of the probability interval. May be less than the probability of the symbols of the symbols may be small to reduce the scope, therefore, are only plus-bit bit less.
