Fast intra prediction mode decision using parallel processing
2005 International Conference on Machine Learning and Cybernetics, 2005H.264 adapts rate distortion optimization (RDO) technique to get high coding rate and visual quality. Because RDO is too much exhaustive, several attempts have been made to explore fast algorithms. In all algorithms computational speed increased with a performance degradation.

A Fast Intra-mode Decision Scheme for HEVC
2014 5th International Conference on Digital Home, 2014Compared with H.264/AVC, the newly published High Efficiency Video Coding (HEVC) standard improves the intra prediction by introducing much more prediction modes and novel techniques, which brings great computational burden. Although the rough mode decision (RMD) scheme in HEVC provides a way to speed up the process, it does not consider the similarity

CNN oriented fast HEVC intra CU mode decision
2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016The real-time requirements of hardwired HEVC encoder demand that, at the grain of coding tree unit (CTU), the maximum computation should be reduced by a fast CU mode decision algorithm. In addition, to realize the parallel rate-distortion optimization (RDO) of different CU modes, the current CU mode decision should not use the auxiliary information ...

Fast Mode Decision for H.264/AVC Using Mode Prediction
2006In this paper, we present a new method to speed up the mode decision process using mode prediction. In general, video coding exploits spatial and temporal redundancies between video blocks, in particular temporal redundancy is a crucial key to compress video sequence with little loss of image quality. The proposed method determines the best coding mode

Fast inter prediction mode decision for H.264
2004 IEEE International Conference on Multimedia and Expo (ICME) (IEEE Cat. No.04TH8763), 2005This paper proposes a fast inter prediction mode decision method for H.264. By pre-encoding a down-sampled small image, the candidate inter block modes can be reduced to a small subset. The experimental result shows that our algorithm can reduce nearly 50% of encoding time with PSNR decrease less than 0 ...

Fast Coding-Unit Mode Decision for HEVC Transrating
2017 IEEE International Conference on Computer and Information Technology (CIT), 2017Transrating is a bitrate transcoding technique that facilitates video applications in heterogeneous environments. This paper presents a fast coding-unit (CU) mode decision algorithm for transrating a once-encoded HEVC bitstreams to lower bitrate versions of diverse quality levels. The proposed method comprises three major parts.

Fast inter-prediction mode decision algorithm for HEVC
Signal, Image and Video Processing, 2016The high efficiency video coding (HEVC) is superior to the previous video coding standards in compression performance, while the computational complexity is introduced simultaneously. The complexity increases mainly due to the novel flexible partitioning scheme that allows the inter-prediction mode partition split via exhaustive rate-distortion ...

Fast convergence dual mode adaptive decision feedback equalization
2008 International Symposium on Information Technology, 2008In this paper, we extend the blind adaptive equalization scheme of Labat, Macchi and Laot that starts up as a linear equalizer (LE) and switches into a decision feedback equalizer (DFE) once the channel eye is open. The modified scheme converges faster and switches more successfully to the DFE under severe equalization conditions such as short filter ...
