Description: 基于DCT域的图像数字水印技术：
摘要：数字水印技术作为数字媒体版权保护的有效办法，近年来在国内外引起了人们极大的兴趣。作者采用了DCT离散余弦变换的算法，对图像这种多媒体数字作品进行了数字水印的嵌入和检测研究。并且使用了高效实用的编程工具MATLAB来介绍了一种DCT域的图像数字水印嵌入和提取的实例，并且在最后对嵌入水印的图像进行了攻击实验，验证了该算法的鲁棒性和不可见性。-Based on the DCT domain image watermarking techniques: Abstract: Digital watermarking of digital media technology as an effective means of copyright protection, in recent years both at home and abroad has aroused great interest. The author adopted the DCT discrete cosine transform algorithms, the image of this multi-media digital works for the digital watermark embedding and detection research. And the use of efficient MATLAB programming tools useful to introduce a DCT domain image watermarking embedding and extraction examples, and in the final of the embedded watermark image of the attack experiments verify the robustness of the algorithm and non- Visibility.

Description: Firstly, research on robust image watermarking. A digital watermarking scheme based on wavelet transform was proposed. It realizes the watermarking extract without the original image using 64×64×8 bit gray image as the watermark signal. In order to enhancing the security of the watermark, we employ an encryption technology based on chaos and bit plan. Simulation results show that our scheme have good invisibility and can survive low-quality JPEG compression, median filtering and so on. In addition, the analysis of the extracted watermark can help us to detect and localize tampers.-Firstly, research on robust image watermarking.
