WebStationary crowd groups are a key factor influencing pedestrian walking patterns but was mostly ignored in the literature. It plays different roles for different pedestrians in a crowded scene and can change over time. In this paper, a novel model is proposed to model pedestrian behaviors by incorporating stationary crowd groups as a key component. Webspammer group can be highly damaging as it can take total control of the sentiment on a product because a group has many people to write fake reviews. Our experiments show …

CiteSeerX — PROFILING STATIONARY CROWD GROUPS

WebIn order to obtain effective crowd relationships for crowd behavior analysis, an adaptive crowd segmentation method based on coherent motion detection is proposed. This method can improve the accuracy of segmentation results and be adaptively applied to various collective scenes that have different distributions at different scales. WebFirst, a stationary crowd detection algorithm is proposed to estimate the stationary time of fore-ground pixels. It employs spatial-temporal filtering and mo-tion filtering in order to be … http://d7.cs.illinois.edu/projects/apo-group-size/ onsip support number
