摘　　要：通过多分辨分析理论,文章在matlab环境下研究了4阶平衡多小波cardbal4在数字水印方面的一种新方法。运用4阶平衡多小波cardbal4在图像中嵌入数字水印,嵌入加密数字水印;再分离图像中的数字水印,及还原加密的数字水印。According to the theory of multi--resolution analysis, a new method to digital watermark- ing on matlab will be studied by balanced multiwavelet cardbal4 in this paper. The digital watermarking will be inserted in the image by by balanced multiwavelet cardbal4. The encryption digital watermarking will be inserted in the image. Then the digital watermarking will be separated from the image with digital watermarking, and the encryption digital watermarking will be reduced.
