一种结合奇异值分解的非下采样剪切波数字水印算法
Digital watermarking algorithm using SVD and non-subsampled shearlet
摘要
Abstract
In order to solve the uncooperativeness between invisibility and robustness,this paper proposed a digital watermarking algorithm using non-subsampled shearlet transform and singular value decomposition to achieve copyright protection for digital images.This algorithm combined the directional features of non-subsampled shearlet transform with the singular value decomposition to embed the binary watermarking into the subband with supremum energy.The algorithm not only satisfied the invisibility and robustness of watermarking algorithm,but also exhibited the superiority compared with previous scheme.Experiment results demonstrate that the values of structural similarity index measurement are approach 1 and average normalized correlation value is above 0.98.Comparing with other similar algorithms,the proposed algorithm has better robust performance.关键词
