基于DCT压缩前后不变量，编写的抗JPEG压缩的数字图像认证水印算法，具有良好的抵抗压缩、剪切、篡改等性能的水印仿真程序-Around the DCT-based compression is not variable, the preparation of the anti-JPEG compression algorithm for digital image authentication watermark with good resistance to compression, shea

在对图像数字水印和图像压缩技术进行深入研究的同时，提 出了在图像压缩域内同时嵌入一个鲁棒水印和一个脆弱水印的双水 印方案-esides researching on the image digital watermarking and image compression technology in—depth，the thesis has put forward a method to embed a robust and af ragile watermark in the

If you re wondering about the number 7 on the equation, the watermark is inserted every 7 pixels. Why not in every pixel? You could, but this way, you can add a second watermark (and a 3rd, and a 4th, etc.) at the same time using the pixels in betwee

基于图像压缩的JPEG图像水印算法，具有较好的安全性-JPEG image compression based image watermarking algorithm, with better security
