Real-time abnormal situation detection based on particle advection in crowded scenes


This paper presents a real-time abnormal situation detection method in crowded scenes based on the crowd motion characteristics including the particle energy and the motion directions. The particle energy is determined by computation of optical flow derived from two adjacent frames. The particle energy is modified by multiplying the foreground to background… (More)
