penCV的全称是：Open Source Computer Vision Library。OpenCV是一个基于（开源）发行的跨平台计算机视觉库，可以运行在Linux、Windows和Mac OS操作系统上。它轻量级而且高效——由一系列 C 函数和少量 C++ 类构成，同时提供了Python、Ruby、MATLAB等语言的接口，实现了图像处理和计算机视觉方面的很多通用算法。-penCV full name is: Open Source Computer Vision Library. OpenCV is based on (open) issued a cross-platform computer vision library, you can run on Linux, Windows and Mac OS operating systems. It is lightweight and efficient- by a series of C functions and a few C++ class structure, while providing an interface Python, Ruby, MATLAB and other languages, to achieve a lot of generic algorithm for image processing and computer vision.
