改进的基于DCT的自适应水印算法
Improved adaptive watermarking algorithm based on DCT.
摘要
Abstract
The paper proposes an improved adaptive algorithm based on DCT according to the characteristics of texture,luminance of original image and the feature of human visual system. The algorithm makes pretreatment of watermarking image with Arnold transform, adaptively chooses scaling parameter of embedding and makes a binary watermarking image embedded into the original image,which implements the robustness and invisibility of algorithm. The experimental results show that this algorithm is robust and stable to common digital image processing operations.关键词
