基于混沌置乱和分形维数的数字水印算法
Digital Watermark Algorithm Based on Chaotic Scrambling and Fractal Dimensions
摘要
Abstract
In this paper,fractal dimensions theory is applied to digital watermark technology,an algorithm based on chaotic scrambling and fractal dimensions is proposed.Firstly,the original image was split into non-overlapping blocks,the fractal dimensions of each blocks was computed.Secondly,the watermark embedding factor is adjusted by fractal dimensions,and the binary watermark image with chaos scrambling is adaptively embedded into the original image's Direct Current(DC) block of DCT domain.Experimental result using MATLAB shows that the algorithm is invisible and has good robustness for some common image processing operations.关键词
