基于小波变换与奇异值分解的图像盲水印算法
A blind watermarking algorithm based on DWT and SVD
摘要
Abstract
This paper presents a new digital image blind watermarking algorithm based on combination of discrete wavelet transform (DWT) and singular value decomposition (SVD) .First of all ,we make wavelet decomposition for the original image and divide the acquired low frequency sub-band into blocks .Then we make singular value decomposition for each block and embed the watermark information in the largest singular value by quantitative method .The watermark can be extracted without the original image .The experimental results show that the algorithm has a good imperceptibility and robustness .关键词
