An Efficient Fast Block Type Selection for Intra prediction in Inter frame of H.264/AVC FRExt
With advanced intra prediction modes, intra coding of H.264/AVC offers significant coding gains compared with previously video coding standards, but the computational burden is extremely high. Recently, H.264/AVC adopts FRExt profile to improve performance in higher-fidelity video, which added intra8×8 predictions. We proposed an efficient fast block type selection algorithm for intra-prediction of H.264/AVC FRExt. The algorithm utilized smoothness feature of blocks to predict the optimal intra block types. By avoiding unlikely block types, the computation can be much reduced. Experimental result shows the proposed algorithm can reduce the computation complexity up to 46.28%, while little PSNR degradation or bit-rate increase.
