The traditional color-based mean shift algorithm is unable to accurately track the object in some challenging scenarios. A mean shift tracker that fuses multiple visual cues is proposed to address the problem. The search region of the object is partitioned into one target region and some background regions according to the estimated location of the object in the previous frame. Then based on the region partition
a novel histogram model is presented for characterizing the color and motion cues. The model can effectively suppress the clutter of adjacent backgrounds. Finally the visual tracker is proposed within the mean shift framework to fuse the color and motion cues so that both. The visual cues can be complemented each other and the accuracy and robustness of tracking is improved. Experiments show that the proposed tracker can obtain more accurate and robust tracking results in some challenging scenarios such as rapid motion
large pose variation or occlusion of objects.
