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用C++语言编写，它的主要接口也是C++语言，但是依然保留了大量的C语言接口。该库也有大量的Python, Java and MATLAB/OCTAVE (版本2.5)的接口。这些语言的API接口函数可以通过在线文档获得。如今也提供对于C#,Ch, Ruby的支持。(OpenCV is a cross platform computer vision library based on BSD license (open source), which can run on Linux, Windows, Android, and Mac OS operating systems. It is lightweight and efficient, consisting of a series of C functions and a small number of C++ classes. It also provides interfaces for languages such as Python, Ruby and MATLAB, and implements many general algorithms for image processing and computer vision.
OpenCV is written in the C++ language, its main interface is also the C++ language, but still remains a large number of C language interfaces. The library also has a large number of interfaces for Python, Java and MATLAB/OCTAVE (version 2.5). The API interface functions of these languages can be obtained by online documents. Today also provides support for C#, Ch, and Ruby.)
