A novel Scheme for the fast inter mode decision of H.264/AVC
نویسندگان
چکیده
The variable block sizes in H264/AVC improve coding efficiency at the price of worsening encoding complexity. To lighten the encoder’s load, a novel fast interframe mode decision Scheme is proposed according to the statistical proportion of each encoding mode. Firstly, check whether the current macro-block is at the skip mode in terms of its characteristics. If so, some encoding modes will be avoided. Secondly, the encoding modes can be further cut down by making use of the correlation between the mode decision and the quantization parameter. Experiments show the proposed scheme can decrease the encoding time up to 31.1-76.1% with less PSNR degradation.

The state-of-the-art video coding standard H.264/AVC achieves significant coding performance improvement by choosing the rate-distortion (RD) optimized encoding mode from a list of candidate modes at the cost of intensive computations, which limits the practical application of H.264/AVC. A number of fast mode decision algorithms have been recently presented in the literature in order to reduce ...

The high performance of H.264/AVC video encoder is accompanied with a wide computation complexity especially for high definition (HD) video sequences. One of the major H.264/AVC features to be optimized is the mode decision for both inter and intra prediction. Thus, based on high correlation observed between selected inter prediction mode and intra mode decision, a fast intra mode decision algo...
