基于奇异值分解的DWT域多重数字水印算法
An algorithm of multiple watermarking based on block singular value decomposition in wavelet domain
摘要
Abstract
In this paper a multiple watermarking algorithm based on the singular value decomposition of matrix in DWT domain is presented.This algorithm enables multiple watermark encoding not interfere with each other by using Hadamard orthogonal transform,which can effectively reduce the watermark embedding capacity and improve the quality of watermark embedding by using the singular value decomposition of matrix.Thus the relation between robustness and imperceptibility can be well balanced.The experiment results show that this algorithm can give better image quality and better robust against noise and commonly used image processing techniques.关键词
