基于fft的数字水印，分别对RBG三个通道重复嵌水印，每个通道分别对fft变换域中幅度谱以圆方式，每个圆上对称的四个点重复嵌1bit水印，然后以r为步进，选更大的圆嵌入接下去的水印信息，该方法有比较好的鲁棒性-Fft-based digital watermarking were embedded watermark repeated RBG three channels, each channel separately the fft transform domain amplitude sp

数字视频处理(光流法、块匹配、视差运动估计和DEW水印嵌入和提取)的例子，整合到一个程序中了。-Digital video processing (optical flow method, block matching motion estimation and disparity DEW watermark embedding and extraction) examples, integrated into a program in it.

这是关于数字水印的嵌入例程！经过调试,可以放心使用！(This is the digital watermark embedding routine!)
