该程序是一个抗打印扫描数字水印算法的仿真，其原理基于DCT域的数据分类，具有很好的效果。原理参考杨义先等编著的《数字水印理论与技术》，高教出版社。(a print-scane watermarking scheme simulation)

将处理过的二进制比特流写入图像，保存显示 (The treated binary bit stream to write the image )

tsne 快速降维算法 效果好于PCA 算法(tsne fast dimensionality reduction algorithm is better than PCA algorithm)

数字图像copy-move篡改检测。特征提取，相似块搜索(detection of copy-move forgery in digitial image)

m_map使用方法详细介绍，采用matlab下载世界地图，可以获取海岸线等数据库(M_map uses the method to introduce in detail, uses the MATLAB to download the world map.)

基于arnold变换加密图像（带解密的代码），缺点是具有周期性(Encryption based on Arnold transform (with decryption code), the disadvantage is cyclical.)

说明：  matlab code for optimization

图像中数字水印matlab编码，水印的嵌入提取及嵌入强度(Digital watermark image matlab coding, the embedded watermark extraction and embedding strength)

实现地震资料的多次波处理,实现相同点的叠加，进而切除(to complish the goal that the noise can be suppressed in the seismic data)

视频水印的matlab源码，文件较多，分为六个压缩包，如果您作相关方向的研究，可用作参考(Video Watermarking Matlab source, the paper more, divided into six compressed, If you made related to the direction of research, can be used as a reference)
