We describe a method for tracking people using a Timeof-Flight camera and apply the method for persistent authentication in a smart-environment. A background model is built by fusing information from intensity and depth images. While a geometric constraint is employed to improve pixel cluster coherence and reducing the influence of noise, the EM algorithm (Expectation Maximization) is used for tracking moving clusters of pixels significantly different from the background model. Each cluster isdoi:10.1109/cvprw.2008.4563156 dblp:conf/cvpr/HansenHKLS08 fatcat:b37muigbjref5onb2nh5fegn2e
