Frame-rate Multi-body Tracking for Surveillance

Abstract

Video surveillance is watching an area for significant events. Perimeter security generally requires watching areas that afford trespassers reasonable cover and concealment. Almost by definition such "interesting " areas have limited visibility distance. These situations call for a wide field of view, and are a natural application for omni-directional VSAM. This paper summarizes our ongoing efforts on developing an omni-directional tracking system. We begin with a few examples and then discuss the background and application constraints. We end with a summary of our approach and its novel components. 1 Examples & Background The paracamera system captures omni-directional video that allows one to generate geometrically correct perspective images in any viewing direction. Figure 1 shows an example. While unwarping in multiple directions and then doing tracking on the perspective images would be possible, it would add considerable expense. Therefore, we are working directly in the complex...
