An Efficient Region-Based Background Subtraction Technique

2008 Canadian Conference on Computer and Robot Vision, 2008
This paper proposes an efficient region-based background subtraction technique using static camera for motion detection in various monitoring applications. Color histograms, texture information, and successive division of candidate rectangular image regions are utilized to model the background and detect the motion.
