This paper proposes an advanced zero-block inter mode decision algorithm for H.264/AVC inter frame coding, to improve computation efficiency of the previous algorithms. Although the previous zero-block decision algorithm in achieves significant computation improvement, computation performance is still limited for high bit-rate coding. To obtain better computation efficiency at high bit-rate, another...
This paper proposes another zero-block inter mode decision algorithm for high bit-rate coding in H.264/AVC, to improve computation efficiency of zero-block decision. In the proposed algorithm we suggest using zero-blocks of both 8×8 and 4×4 zero-blocks to describe video sequences in detail, including global and local stationary characteristics. The experimental results reveal that significant computation...

The variable block size motion estimation (ME) and compensation (MC) using multi-reference frames is adopted in H.264/AVC to improve coding efficiency. However, the computational complexity of the ME/MC increases proportional to the number of reference frames. In this paper, we propose a new efficient reference frame selection algorithm to reduce the complexity. The proposed algorithm selects suitable...
Multiple reference frames motion estimation is one of the new features introduced in H.264/AVC. Although this new feature improves video coding performance, it is extremely computational intensive. Full search scheme is adopted in reference software JM, and the increased computation load is in proportion to the number of searched reference frames. In this paper, we propose a novel fast multiple reference...
H.264 adopts variable block size motion estimation and rate-distortion-optimization based mode decision to improve video quality and compression ratio. These techniques have made H.264 better than other existing video coding standards. However, they are computationally intensive and time-consuming. In this paper, a fast mode selection scheme is proposed for H.264 inter prediction. Firstly, the first...
Based on the statistical analysis of relation between CBP (Coded Block Pattern), MVD (Motion Vector Difference) and each coding mode, a fast mode selection algorithm based on macroblock-adaptive is proposed. In this algorithm, adaptive judgment strategies are adopted to filter partial coding mode quickly. The residual CBP, MVD information is used adequately to identify the relativity of intra and...
The improvement in compression efficiency of H.264 has brought about the dramatic increase in computational complexity. This makes it be a must to reduce the computational complexity of algorithms in real time applications. The algorithm of the inter mode decision is key technology in H.264/AVC video coding standard. By analyzing a statistical result of percentage of optimal modes according to different...
