We proposed a robust approach to object motion estimation between frames based on block matching in this paper.Compared with existing methods for object motion estimation between frames

our approach

firstly

employs color information to improve accuracy of block matching;secondly

by adopting a wide range of adaptive scheme

the robustness and high efficiency of the proposed approach can be achieved; finally

prediction correction based compound search algorithm integrates history information of object motion together with advantages of three step search algorithm andfull search algorithm to yield efficient andaccurate motion estimation.Experiment results demonsrate that the proposed approach can track objects moving in a very complex background or that in a low SNR environment

so our approach can achieve more robust motion estimation thanexisting block matching based methods.
