Abstract : In the newest video coding standard of H.264, intra frame prediction is conducted in the spatial domain. There are two types of intra prediction for luma -- Intra_16x16 does prediction for the whole 16x16 luma macroblock and Intra_4x4 does prediction for 4x4 block. Four and nine modes are supported by Intra_16x16 and Intra_4x4, respectively. The Full Search algorithm is used in the JVT reference software to choose the best modes, however it is very computationally expensive. In this paper, a new fast intra prediction algorithm using macroblock properties (FIPAMP) is proposed. Experimental results show that the proposed fast algorithm can achieve 10% to 40% computation reduction while maintaining similar PSNR and bit rate performance of H.264 codes.
