摘要：

A new block based motion estimation and compensation technique named overlapped multi-resolution motion compensation (OMRMC) is proposed. The algorithm employs the overlapped block motion compensation (OBMC) algorithm in wavelet domain to reduce the blocky artifacts in the predicted frames using the multi-resolution motion estimation (MRME) technique. Simulation results showed the use of OMRMC reduced up to 26% of the displaced frame difference (DFD) energy compared with MRME.
