Abstract : A novel motion compensated temporal filtering (MCTF) scheme is proposed in this paper by properly using forward and backward motion compensation. All the mean, the second moment and the maximum value for the temporal distance of all motion compensation pairs (MCPs) in a group of frames (GOF) are minimized such that the number of ``unconnected" pixels is minimized. The overall coding efficiency is improved by up to 1.5dB when compared to the scheme provided in [2] while the total number of motion estimation remains the same.
