基于OPenCV的源码，实现了OpenCV中存储器的操作，包括读和写等。,OPenCV based on the source, the OpenCV implementation of the operation of memory, including read and write and so on.

从显存读图像,基于opencv写的，需要安装opencv进行配置调试。 -Reading images from memory, based on opencv.You need to install opencv to debugging.

canny算子的c++写法，不依赖opencv的库函数，对图像的存储释放都包含在内-canny operator c++ writing, opencv library functions do not rely on memory to release images are included
