Robust target detection and tracking through integration of motion, color, and geometry

Vision-based tracking is a basic elementary task in many computer vision-based applications such as video surveillance and monitoring, sensing and navigation in robotics, video compression, video annotation, and many more. However, reliable recovery of targets and their trajectories in an uncontrolled environment is affected by a wide range of conditions exhibited by the environment such as sudden illumination changes and clutter. This work addresses the problem of (i) combining information from a set of cues in order to obtain reasonably accurate estimates of multiple targets in uncontrolled environments and (ii) a collection of data association methods for cues containing less information for robust tracking through persistent clutter. Specifically, we introduce a novel geometric template constrained data association method for robust tracking of point features, while using the Joint Probabilistic Data Association (JPDA) method for blob cue measurements. Extensive experimental valid...
