Abstract

In this paper, a fast intra mode decision algorithm based on transform-domain property is proposed to reduce the coding complexity in H.264/AVC encoder. According to the basis patterns for DCT transformation, the 4×4 block is first transformed and then the transformed coefficients are utilized to detect the tendency of target block. In comparison to the previous fast mode decision algorithms, which measure the edge direction by complex arithmetic operations, the proposed algorithm simplifies the procedure of detection method. Experimental results show that the proposed algorithm can support more accurate prediction in the least bit-rate increment, which outperforms the intra coding time approximately by 55% of the full search method.
