Learning a background model for change detection.

Change detection or foreground background segmentation, has been extensively studied in computer vision, as it constitutes the fundamental step for extracting motion information from video frames. In this paper, we present a robust real-time foreground /background segmentation system employing a Chebyshev probability inequality based background model, supported with peripheral and recurrent motion detectors. The system uses shadow detection, and relevance feedback from higher-level object tracking and object classification to further refine the segmentation accuracy. Experimental results on wide range of test videos demonstrate the high performance of the presented method with dynamic backgrounds, camera jitter, cast shadows, as well as thermal video.
