基于提升小波变换的自适应盲水印算法
Adaptive Blind Watermark Algorithm Based on Lifting Wavelet Transform
摘要
Abstract
This paper proposes a kind of adaptive blind watermark algorithm based on lifting wavelet transform. The watermark is encrypted through new arnold transform, and the original image is decomposed through lifting wavelet transform. Three high frequency coefficients of corresponding locations in the same level are sorted, and come into being a section between the maximum and the minimum which is divided into 2Q-1 sub-sections. The eigenvalue is in the different sub-zone, when the information embedded is different. The watermark can be extracted according to the locations of eigenvalue. This is a kind of blind watermark extracting method. Experimental result shows that this algorithm has a good robustness and recognizable character under many kinds of assaults.关键词
