Relative discriminant coefficient based multi-cue fusion for robust object tracking

Abstract

In visual tracking, integrating multiple cues will increase the reliability and robustness of the tracking system in situations where no single cue is reliable. In this paper, a novel multi-cue based tracking method is presented under the particle filter framework. Considering both practical distance and Bhattacharyya distance between particles and the target, a parameter called relative discriminant coefficient (RDC) is designed to measure the tracking ability for different features. Multi-cue fusion is carried out in a reweighing manner based on this parameter. Experimental results demonstrate the high robustness and effectiveness of our method in handling appearance changes, cluttered background, illumination changes and occlusions.
