BGSLibrary

BGSLibrary: A Background Subtraction Library

Release License: GPL v3 Platform: Windows, Linux, OS X OpenCV Wrapper: Python, MATLAB Algorithms

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

3.3.0 (see Build Status and Release Notes for more info)

Background and Development

The BGSLibrary was developed in early 2012 by Andrews Cordolino Sobral 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, making it free for both academic and commercial use.

Getting started

#include <iostream>
#include <algorithm>
#include <iterator>
#include <vector>

// Include the OpenCV and BGSLibrary libraries
#include <opencv2/opencv.hpp>
#include <bgslibrary/algorithms/algorithms.h>

int main( int argc, char** argv )
{
    // Gets the names of the background subtraction algorithms registered in the BGSLibrary factory
    auto algorithmsName = BGS_Factory::Instance()->GetRegisteredAlgorithmsName();

    // Displays the number of available background subtraction algorithms in the BGSLibrary
    std::cout << "Number of available algorithms: " << algorithmsName.size() << std::endl;

    // Displays the list of available background subtraction algorithms in the BGSLibrary
    std::cout << "List of available algorithms:" << std::endl;
    std::copy(algorithmsName.begin(), algorithmsName.end(), std::ostream_iterator<std::string>(std::cout, "\n"));

    // Returns 0 to indicate that the execution was successful
    return 0;
}

Installation instructions

You can either install BGSLibrary via pre-built binary package or build it from source

Supported Compilers:

  • GCC 4.8 and above
  • Clang 3.4 and above
  • MSVC 2015, 2017, 2019 or newer

Other compilers might work, but are not officially supported. The bgslibrary requires some features from the ISO C++ 2014 standard.
