discrete wavelet and svd based watermarking with 12 type of attack included

需要指出的是，还存在改进算法的速度和内存使用的空间，比如用于RQ分解的位移结构算法和svd的Lanczos算法。在这个软盘上实现的算法只使用基本的MATLAB命令(没有花哨的优化c代码)。请随意改进，让我知道您的想法:(The algorithms that have been implemented on this diskette only use basic MATLAB commands (and no fancy optimized C-code). Feel free to i
