 The **BGSLibrary** was developed early 2012 by [Andrews Sobral](http://andrewssobral.wixsite.com/home) to provide an easy-to-use C++ framework (wrappers for Python, Java and MATLAB are also available) for foreground-background separation in videos based on [OpenCV](http://www.opencv.org/). The bgslibrary is compatible with OpenCV 2.4.x, 3.x and 4.x, and compiles under Windows, Linux, and Mac OS X. Currently the library contains **43** algorithms. The source code is available under the [MIT license](https://opensource.org/licenses/MIT), the library is available free of charge to all users, academic and commercial.
