DPCM编码是预测编码的一种,这是一个用MATLAB实现DPCM编码的方法.-the development of dpcm with matlab,DPCM is a method of cmprises of the image.This is a program of dpcm with the matlab

本代码由matlab语言编写，实现了jpeg算法，主要为了说明基本的JPEG功能。经过DCT变化，量化，进行DPCM编码，然后之字形扫描AC系数，进行行程（LZW）编码。 显示原始图象和经编码解码后的图象，显示压缩比，并计算均方根误差。-The code consists of matlab language, to achieve a jpeg algorithm, mainly to illustrate the basic functionality of JPEG. After chan
