JPEG图像压缩及还原实例源代码 非常值得研究一下-JPEG image compression and restore the source code examples are very worthy of study! ! !

GIF图片解压成RGB格式的程序，可根据需要，转成灰阶或其它格式-GIF images into RGB format decompression procedures can be, converted into gray-scale or other format

这是一个关于基于混合编码的图象压缩技术的实现，现在勉强可以实现关于小波的图象压缩实现。此程序可以将BMP格式的图象经压缩后以JPG的格式存储起来！压缩比一般可以达到32:1。还可以显示编码压缩所耗时间-This is a mixed coding on the basis of the image compression technology, and now can barely be achieved on wavelet image compression achieved. This procedure can be BMP format images compressed by the JPG format to store up! Compression ratio generally can be reached 32:1. It also shows the time taken Coding

LZ77压缩算法是一种无损数据压缩算法。该算法是大多数 LZ 算法变体如 LZW、LZSS 以及其它一些压缩算法的基础。是基于字典的编码器。-LZ77 compression algorithm is a lossless data compression algorithm. The algorithm is most LZ algorithm variants, such as LZW, LZSS compression algorithm, as well as some other basis. Is based on the dictionary encoder.
