一种基于信息压缩的图像小波域水印算法
A Image Wavelet Domain Watermarking Algorithm Based on Information Compression
摘要
Abstract
To improve the imperceptibly of watermark, a image wavelet domain watermarking algorithm is proposed based on information compression. Through technologies of thinning image and skeleton scaling, the size of embedded data is reduced The compressed watermarking is embedded into the loweast frequency subband after three levels wavelet decomposition of the image and can be extracted through a reverse process. The embedded watermarking has properties of high imperceptibility and good robust. Simulation experiment shows that the algorithm has good imperceptibility and the watermark can be well extracted for filtering attack, noise attack, image compression attack and cutting attack.关键词
