软件介绍

信息隐藏课程做的基于量化索引(抖动调制)的水印嵌入与提取,内容如下: 1. 空域的嵌入与提取(黑白图) 2. 包含DCT变化与量化的水印嵌入与提取(彩色图) 3. 6种攻击测试(高斯噪声,放大攻击,裁剪,平移,像素值修改,旋转) 4. psnr计算 5. 探究量化表的修改

Information hiding based on quantization index modulation (jitter) courses do watermark embedding and extraction, the content is as follows: 1. The airspace of embedding and extraction (black and white picture) 2. Include changes in DCT and quantization watermark embedding and extraction (color chart) 3. 6 kinds of attack test (gaussian noise, enlarge attacks, cutting, translation, pixel value changes, rotation) 4. PSNR calculation 5. Explore quantitative table changes.
