摘要

In real-world target tracking scenarios, interactions among multiple moving targets can severely compromis the performance of the tracking system. Targets involved in interactions are typically closely-spaced and ai often partially or entirely occluded by other objects. In these cases, valid target observations are unlikely to b available. To address this issue, we present an integrated multi-target tracking system. The data associatio method evaluates the overlap rates between newly detected objects (target observations) and already-tracke targets, and makes decisions pertaining to whether a target is interacting with other targets and whether it ha a valid observation. Thus, the system is capable of recognizing target interactions and will reject invalid targe observations. According to the association results, distinct strategies are adopted to update and manage th tracks of interacting versus well-isolated targets. Testing results on real-world airborne video sequences demon strate the excellent performance of the proposed system for tracking targets with multiple target interactions Moreover, the system operates in real time on an ordinary desktop computer.
