一种基于Arnold和量化的DCT域盲水印算法
A DCT domain blind watermarking algorithm based on Arnold and quantification
摘要
Abstract
A DCT domain blind watermarking algorithm was proposed based on Arnold and quantification. Firstly Arnold chaotic scrambling to the watermarking is conducted before the embedding to reduce the correlation between pixels and improve the security of the watermarking; then according to the bit values of watermarking which is to be embedded, different methods are used to quantize the frequency coefficient of each sub-block; and then based on the coefficient characteristics of embedding watermarking, the watermarking is extracted in which the watermarking extraction process does not require the original image so as to achieved the blind extraction. Numbers of experiments show that the algorithm has good robustness and transparency in cope with common attacks.关键词
