There are three major issues for visual object trackers: model representation, search and model update. In this paper we address the last two issues for a specific model representation, grid based distribution models by means of channel-based distribution fields. Particularly we address the comparison part of searching. Previous work in the area has used standard methods for comparison and update, not exploiting all the possibilities of the representation. In this work we propose two comparison schemes and one update scheme adapted to the distribution model. The proposed schemes significantly improve the accuracy and robustness on the Visual Object Tracking (VOT) 2014 Challenge dataset.
