Count correlation of discrete signals

是图像处理中奇异值分解的代码，对图像处理很有用。(Is the singular value decomposition of the image processing code, useful for image processing.)

本程序是ldpc的C语言源代码，如果有需要可以下载学习，可以学习整个通信框架(This program is ldpc the C language source code can be downloaded if there is a need to learn, you can learn the entire communication framework)

说明：  与基于函数的边缘检测不同，本程序是基于逻辑运算实现图像的边缘检测(Edge detection based on different functions, this program is based on the logic operation of image edge detection)
