Flow Segmentation in Dense Crowds
Now a day’s security is an important aspect to be considered, so a framework is proposed in this paper that is used to segment flow of dense crowds. The flow field that is generated by the movement in the crowd is treated just like an aperiodic dynamic system. On this flow field a grid of particles is put over for particle advection by the use of a numerical integration scheme. Then flow maps a...

متن کاملLaser-based detection and tracking of multiple people in crowds
Laser-based people tracking systems have been developed for mobile robotic, and intelligent surveillance areas. Existing systems rely on laser point clustering method to extract object locations. However, for dense crowd tracking, laser points of different objects are often interlaced and undistinguishable due to measurement noise and they can not provide reliable features. It causes current sy...
متن کاملLocal Segmentation for Pedestrian Tracking in Dense Crowds
People tracking in dense crowds is challenging due to the high levels of inter-pedestrian occlusions occurring continuously. After each successive occlusion, the surface of the tracked object that has never been hidden reduces. If not corrected, this shrinking problem eventually causes the system to stop as the area to track become too small. In this paper we investigate how hidden parts of one...
متن کاملDetecting and Tracking Coordinated Groups in Dense, Systematically Moving, Crowds
We address the problem of detecting and tracking clusters of moving objects in very noisy environments. Monitoring a crowded football stadium for small groups of individuals acting suspiciously is an example instance of this problem. In this example the vast majority of individuals are not part of a suspicious group and are considered as noise. Existing spatio-temporal cluster algorithms are on...
