通过MATLAB 仿真实现哈夫曼编码的图片压缩(MATLAB Simulation by Huffman coding of image compression)

说明：  视频信号的压缩处理，包括帧分类，冗余的去除等(Video signal compression, including frame classification, redundancy removal, etc.)

核概率密度估计算法，对于以往的有优化，可以得到概率密度及分布函数。(Nuclear probability density estimation algorithm optimized for the past there, you can get the probability density and distribution functions.)

离散时间的基本运算，是MATLAB函数改进增强版本，更加的实用，包括卷积，折叠等基本运算(Discrete-time basic operations, is an enhanced version of MATLAB function improved, more practical, including convolution, folding and other basic operations)

因子图和和积算法的matlab实现，给需要的人用，谢谢你的宝贵建议(factor graph and sum-product algorithm )

说明：  本课题基于MATLAB平台的数字信号处理仿真演示系统。数字信号即离散信号，本设计带有一个丰富得GUI人机交互界面，一共包括4个部分，分别为：离散时间信号的卷积，基本函数的Z变换（单位阶跃信号，脉冲信号，斜变信号，正余弦信号，指数系列信号），Z变换的基本性质（线性，位移，z域尺度变换，时域卷积），傅里叶变换的基本性质。是一个不错的选题，GUI设计逻辑清晰，章节清晰，层次明了。(This project is based on MATLAB platform of digital signal processing simulation demonstration system. Digital signal is discrete signal. This design has a rich GUI human-computer interface, including four parts: convolution of discrete-time signal, Z-transform of basic function (unit step signal, pulse signal, oblique signal, sine cosine signal, exponential series signal), basic properties of Z-transform (linear, displacement, z-domain scale transformation, time-domain convolution), The basic properties of Fourier transform. GUI design logic is clear, chapter is clear, level is clear.)

说明：  语音信号的数字滤波处理 加入高斯噪声再滤除,信噪比小于20分贝(Voice signal digital filter handle add further filtered Gaussian noise, signal to noise ratio is less than 20 dB)
