A Heat-Map-based Algorithm for Recognizing Group Activities in Videos

21 Feb 2015Weiyao LinHang ChuJianxin WuBin ShengZhenzhong Chen

In this paper, a new heat-map-based (HMB) algorithm is proposed for group activity recognition. The proposed algorithm first models human trajectories as series of "heat sources" and then applies a thermal diffusion process to create a heat map (HM) for representing the group activities...
