This study presents a fast intra-prediction algorithm for a high-profile H.264 encoder. First, a pre-decision algorithm is proposed to reject the impossible block size based on image variance. Then a fast 4 × 4 block prediction algorithm is proposed to select four possible modes from nine predicted modes based on the edge-filtering detection. With a hierarchical approach, the 8 × 8 block prediction is based on the result of the chosen 4 × 4 block mode. This approach selects only one to five… CONTINUE READING
