Discover background subtraction and BMC

You can use BMC to know how to use background subtraction thanks to OpenCV. This tutorial will help you to discover background subtraction, thanks to some videos available in BMC. To get more algorithms, we also recommend you to use the BGSLibrary, offering a lot of advanced background subtraction techniques.

Background Models Challenge (BMC) is a competition for the comparison of background subtraction algorithms. The main topics of our workshop are

  • detection of moving objects, motion
    estimation ;

  • background / foreground modeling ;

  • signal, image processing ;

  • image segmentation ;

  • intelligent video-surveillance.

Many real-time vision-based applications devoted to video surveillance search for distinguishing moving objects from an image sequence given by a static camera. This background/foreground segmentation stage could be addressed by simple approaches, e.g. by computing the difference between two successive frames, or by building a time-averaged background image. However, such simple algorithms are very limited in outdoor environment for instance (because of global variation of luminance, shadows of objects, etc.).

Since this is an important step in video analysis, many background subtraction algorithms have been proposed since 90’s to tackle these problems. Although the evaluation of BSA is an important issue, relevant papers that handle with both benchmarks and annotated dataset are limited. Moreover, many authors that propose a novel approach use classic techniques as a gold-standards, but rarely compare their method with recent related work. BMC is thus an opportunity for researchers at both universities and companies to evaluate the quality of their work.
