A Diffusion and Clustering-based Approach for Finding Coherent Motions and Understanding Crowd Scenes
Statistical Hypothesis Detector for Abnormal Event Detection in Crowded Abstract Abnormal event detection is now a challenging task, especially for crowded scenes. Many existing methods learn a normal event model in the training phase, and events which cannot be well represented are treated as abnormalities. However, they fail to make use of abnormal event patterns, which are elements to comprise abnormal events. Moreover, normal patterns in testing videos may […]
