Considering the video sequences with a single moving object,this paper proposed a new fast block matching motion estimation approach,which combining C-1BT transformation and the ARPS approach.The proposed pre-processing step was simple,and could increase the robustness of the global motion estimation in the intensity suddenly changed and existence of local motion of objects.Then,it used a simplified C-1BT transformation kernel function to reduce the computational burden.In the search process,improved ARPS algorithm not only used spatial correlation,but also used a lot of early termination of the search methods.MATLAB simulation results show that the proposed approach can greatly reduce the search points while ensuring accuracy.
