Description: 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 Platform: |
