基于奇异值分解的多通道彩色图像数字水印算法

Multi-channel Color Image Digital Watermarking Algorithm Based on SVD

一种基于SVD奇异值分解的的自适应彩色图像数字水印算法,利用FCM自适应的选择合适水印嵌入的小波块,对选取的小波块进行SVD分解,得到每个分块的奇异值,选取每块最大的奇异值,并进行排序。利用混沌序列进行混沌置乱,最后实现水印的嵌入。

An adaptive color image digital watermarking algorithm based on SVD,using FCM to choose a wavelet block fitting embedding watermark.Do SVD for each selected block,and get the SV for each block,then choose the maximum SV and order them.Making use of chaotic sequences to do chaotic scrambling,and finally it realizes the embedding of watermark.
