Human sensing is a critical technology to achieve surveillance systems, smart interfaces, and context-aware services. Although various vision-based methods have been proposed (Aggarwal & Cai, 1999)(Gavrila, 1999)(Yilmaz et al., 2006), tracking humans in a crowd is still extremely difficult. Figure 1 shows a snapshot of a railway station during rush hour, which is one of the hardest examples of human sensing.
