OpenCV是一个基于BSD许可（开源）发行的跨平台计算机视觉库，可以运行在Linux、Windows、Android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。(OpenCV is a cross platform computer vision library based on BSD licensing (open source) that can run on Linux, Windows, Android, and Mac OS operating systems. It is lightweight and highly efficient, composed of a series of C function and a small amount of C++, Python, Ruby, and MATLAB language interface, implements many common algorithms of image processing and computer vision.)
