## Introduction
The **BGSLibrary** (Background Subtraction Library) is a comprehensive C++ framework designed for background subtraction in computer vision applications, particularly for detecting moving objects in video streams. It provides an easy-to-use and extensible platform for researchers and developers to experiment with and implement various background subtraction techniques.
## Library Version
**3.3.1** (see **[Build Status](https://github.com/andrewssobral/bgslibrary/wiki/Build-status)** and **[Release Notes](https://github.com/andrewssobral/bgslibrary/wiki/Release-notes)** for more info)
## Background and Development
The BGSLibrary was developed in early 2012 by [Andrews Cordolino Sobral](http://andrewssobral.wixsite.com/home) as a C++ framework with wrappers available for Python, Java, and MATLAB. It aims to facilitate foreground-background separation in videos using the OpenCV library.
## Compatibility
The library is compatible with OpenCV versions 2.4.x, 3.x, and 4.x. It can be compiled and used on Windows, Linux, and Mac OS X systems.
## Licensing
The library's source code is available under the [MIT license](https://opensource.org/licenses/MIT), making it free for both academic and commercial use.

Would you bet a product on this? Bounded 0–100 and slow moving.
