Robust background subtraction using data fusion for real elevator scene

Abstract

This paper proposes a background subtraction technique robust in elevator environments. Sudden local illumination changes arise frequently in an elevator environment due to opening and closing of the elevator door as well as the inner walls of elevator being made of reflective materials. We present a novel method sequentially fusing a Gaussian mixture model for background subtraction, motion information and a spatial likelihood model based on textured features. Experimental results on real video data demonstrate effectiveness of the proposed approach. © 2011 IEEE.
