| Abstract(in English) | This paper describes an efficient motion compensation (MC) method using edge adaptive motion vector interpolation. In the proposed method, interpolation is adaptively performed according to the presence of a segment boundary between control grids. The segment shape of the current frame is predicted from segmentaion results of the reference frame and the control grid motion vectors for the current frame. Here, segment shape information does not need to be coded, since the reference frame is the local decoded picture. Simulation results show that edge adaptive motion vector interpolation significantly improves the prediction performance especially at segment boundary. The SNR of the coded sequence obtained using the proposed MC method is about 1.7 dB higher than that using the conventional block-based one. |
