Description
This work proposes a novel INTRA coding algorithm which can achieve high coding efficiency using temporal-spatial prediction for H.264/AVC. The proposed prediction algorithm can compensate the weak point of individual usage of spatial or temporal prediction. Firstly, a new prediction block is selected in the temporal previous frame. Next, the selected block in the previous frame is used as the reference data to perform spatial prediction with the same reference direction as traditional INTRA modes. The coding process can also be reconstructed in decoder side without additional bit transfer. The simulation results show that the proposed new INTRA modes can achieve about 1dB improvement than the original H.264/AVC.
