实现视频实时拼接，基于opencv和cuda编程，能实现实时行(Real-time video splicing, based on OpenCV and CUDA Programming, can realize real time line)

将图片首先利用opencv转换为二值图像，突出线条，在进行图片线条提取、(First, the picture is converted to a two value image with a opencv, the line is highlighted, and the line extraction is performed.)

基于傅里叶变换的数字盲水印加解密 加密文件encode-python.py, 解密文件decode-python.py 依赖环境：python+opencv 命令行参数 encode： --image [源文件] --watermark [水印文件] --result [生成目标文件地址] [--alpha 混杂强度] decode: --original [源文件] --image [待解密文件] --result [水印生成文件地址](Digital blind wate
