A quadratic programming method with network flow constraints is proposed to improve crowd pedestrian counting in video surveillance. Most of the existing approaches estimate the number of pedestrians within one frame, which result in inconsistent predictions in temporal domain. In this paper, firstly, we segment the foreground of each frame into different(More)
Recently, a directed graph model was presented to crowd counting in videos, and people flow was viewed as an integer flow on the constructed graph. The authors show that the network flow constraints on the graphs help to obtain consistent counting results. In this paper, we improve their work from two aspects. First, we design block histogram features for(More)
