Graphical Model based Cue Integration Strategy for Head Tracking
Xian Zhong, Jianru Xue, Nanning Zheng · 2006
To achieve robust system, more and more vision researchers take into account fusing multiple visual cues. In this paper, we propose a novel strategy to integrate multiple naive cues for head tracking. Firstly, a cue dependency model is constructed via graphical model. Secondly, a new inference procedure based on non-parametric belief propagation is built for cue integration. The work presented is thus a general framework easy to extend for other computer vision research problems. Experimental results imply that the strategy we propose is effective, and it is robust without estimation of cue reliability. 1
