PSO-Matlab

这是数字水印算法中最简单的LSB算法,实现了嵌入和提取,验证可以正确运行.测试运行环境为:matlab6.5(This is the digital watermarking algorithm LSB most simple algorithm, and the embedding and extraction. Verification can correct operation. runtime environment for testing : matlab6.5)

图像的压缩，很好用，有程序。希望站长尽快审核通过，急需一点资料(Image compression, and very easy to use program. Hope that the webmaster as soon as possible for approval in urgent need of a little information)

cdi_readfield.m cdi_readfield.mcdi_readall.mexw32 cdi_readfull.mexw32 cdi_readfield.m matlab的一些程序，希望大家在学习中可以用到(matlab studying)

The program open any file with hex format.and ascii code translate to right if they are visiable!
