DM642的H.264编码，钛

基于matlab的小波变换的图象压缩，每个子程序有详细的说明。-based on Matlab Wavelet image compression, each subroutine with detailed explanations.

输入8个字符（数目可以自己设定，需要改动程序中N的值），注意空格也算字符，然后输入权值，会显示构造的霍夫曼树及每个字符的编码-Encode：enter 8 characters，then enter 8 numbers，this program will print the huffman tree and each char s code.

图象轮廓提取 比较简单 是本人在MATLAB环境下编译的-image contour extraction is relatively simple I MATLAB environment in the compiler

自己用C语言编写的一个算术编码的程序，很好用的。-own use of the C language an arithmetic coding procedures, very good use.

很好地，希望大家都来看看，关于RS－485方面的知识和串口方面的。-Well, we want everyone to look at it, on the RS-485 serial port of knowledge and respect.

vc编写的实现圆形时钟的程序,时钟显示系统时间-vc prepared by the round the clock to achieve the procedure, the clock time display system

我在做项目的时候需要将文件进行压缩和解压缩，于是就从http://www.icsharpcode.net下载了关于压缩和解压缩的源码，但是下载下来后，面对这么多的代码，一时不知如何下手。只好耐下心来，慢慢的研究，总算找到了门路。针对自己的需要改写了文件压缩和解压缩的两个类，分别为ZipClass和UnZipClass。其中碰到了不少困难，就决定写出来压缩和解压的程序后，一定把源码贴出来共享，让首次接触压缩和解压缩的朋友可以少走些弯路。-When I was doing the project will need to compress and decompress files, so downloading from http://www.icsharpcode.net on the compression and decompression of the source code, but it downloaded, and faced with so many code, 1:00 do not know how start with. Had under-resistant heart, the slow research and finally found the avenues. In light of their need to be rewritten a file compression and decompression of the two classes, namely ZipClass and UnZipClass. Which encountered many difficulties, it was decided to write out compression and decompression process, some paste out of the source code sharing, so that the first contact with compression and decompression of friends can take some less roundabout.

MATLAB(DCT+DWT)图像数字水印的方案毕业论文,基于dct和dwt的算法,有详细程序-MATLAB (DCT+ DWT) image watermarking program thesis, based on the DCT algorithm and dwt, has detailed procedures

这是一个JPEG解码器,里面使用了MMX,SSE等汇编指令集

此源码为按照jpeg标准编写的huffman压缩程序源代码，主要是进行图像数据压缩-source of this according to jpeg standards prepared by the Huffman compression source code, mainly for image data compression
