基于视觉密码的彩色图像水印。认证信息由标记的密码、水印和密码生成。-Visual cryptography based color image watermarking. Authentication information generated by the tag code, watermark and password.

lsb空域水印算法，dct水印算法，dwt水印算法，处理灰度水印以及彩色图像水印，同时还有字符水印嵌入音频中。分别有着三个GUI界面实现不同功能。欢迎批评指正！-lsb airspace watermarking algorithm, dct watermarking algorithm, dwt watermarking algorithm, the watermark process grayscale and color images watermarking, as well as th

在彩色图像中嵌入二值灰度水印。有两种算法，第一种嵌入在yuv模型的y层整体系数上，第二种嵌入在rgb模型r层直流系数上。本科毕设题目，希望可以帮到你。(Two valued gray watermark is embedded in color image. There are two algorithms. The first one is embedded in the overall coefficients of the Y layer in the YUV model, and the
