奇异值分解算法的m代码，实现了数字水印技术的嵌入及提取过程，效果不错。-Singular value decomposition algorithm m code, the realization of the digital watermark embedding and extraction technology process, good results.

this matlab code for the paper solved on the DWT SVD and DCT -this is matlab code for the paper solved on the DWT SVD and DCT

对读入的图像做奇异值分解，观察各阶的基图像。-Read the image and do the singular value decomposition,observe the base image .
