BGSLibrary is a C++ framework for background subtraction in video, offering 43 algorithms for foreground-background separation built on OpenCV. It includes wrappers for Python, MATLAB, and Java, plus a Qt-based GUI, and works on Windows, Linux, and macOS.

Use cases

• detect moving objects in video streams
• separate foreground from background in surveillance footage
• compare background subtraction algorithms on benchmark videos
• use background subtraction from Python with OpenCV
• build a people or vehicle counter from camera video
• experiment with motion detection algorithms in C++

When to choose

• you need many background subtraction algorithms behind one API
• you want OpenCV-compatible C++ code with Python bindings
• you're researching or benchmarking foreground detection methods
• you need MIT-licensed code usable in commercial projects

When to avoid

• you need deep-learning-based video segmentation rather than classical methods
• you want a ready-made application rather than a library to integrate
• your project doesn't use OpenCV and you can't add it as a dependency
