Sector Based Multiple Camera Collaboration for Active Tracking Applications

Abstract

This paper presents a scalable multiple camera collaboration strategy for active tracking applications in large areas. The proposed approach is based on distributed mechanism but emulates the master-slave mechanism. The master and slave cameras are not designated but adaptively determined depending on the object dynamic and density distribution. Moreover, the number of cameras emulating the master is not fixed. The collaboration among the cameras utilizes global and local sectors in which the visual correspondences among different cameras are determined. The proposed method combines the local information to construct the global information for emulating the master-slave operations. Based on the global information, the load balancing of active tracking operations is performed to maximize active tracking coverage of the highly dynamic objects. The dynamics of all objects visible in the local camera views are estimated for effective coverage scheduling of the cameras. The active tracking synchronization timing information is chosen to maximize the overall monitoring time for general surveillance operations while minimizing the active tracking miss. The real-time simulation result demonstrates the effectiveness of the proposed method

A knowledge based infrared camera system for invisible gas detection utilizing image processing techniques

“…One must adjust the tile size and function parameters to maximize contrast and structural visibility whenever images are acquired. Adjacent tiles are merged using bilinear interpolation to eliminate artificially induced boundaries (Hong et al 2017). Figure 4 shows the 100th frames of input image sequences in various circumstances as examples.…”
