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
-DCT domain of image-based digital watermarking technology: Abstract: digital watermarking technology as an effective way of copyright protection of digital media, both at home and abroad in recent years has aroused great interest of the people. The DCT discrete cosine transform algorithm of digital watermark embedding and detection, the image of this multimedia digital works. Practical and efficient programming tools and use MATLAB to introduce a DCT domain image watermarking embedding and extracting
