In order to improve the robustness of the distribution fields(DF)as an object model in object tracking,we propose a mutli-feature fusion framework for the distribution fields.In the original DF-based method,the density histogram was used to estimate the DF of a pixel,but the structural information was ignored.For effective representation of the structural information in the DFs,a special type of coding for the featured points which contain structural information is merged into the DFs.Experiments show that the new method outperforms the original method and four other state-of-the-art tracking algorithms for some challenging video clips.
