H.264/AVC supports various block sizes for intra prediction to reduce spatial redundancy such as 4times4, 8times8 (FRExt only) and 16times16, and the blocks are predicted from neighboring reconstructed pixels by using directional prediction modes. The directional prediction mode indices are coded by using a predictive coding method, in which the most probable mode (MPM) is derived from neighboring...
CABAC is the entropy coding method adopted in H.264/AVC main profile. The combination of CABAC and RDO can represent an improvement in bit rate of around 20%. However, the computation complexity of video encoding increases drastically. To improve the coding performance, this paper proposes a transform-domain bit-rate estimation method for CABAC, which estimates the bit-rate of coding blocks based...
