Fast intra mode decision for depth map coding
2013 IEEE International Symposium on Consumer Electronics (ISCE), 2013Nowadays, JCT-3V joined by ITU-T VCEG and ISO/IEC MPEG is developing new 3D video coding standard, MVC+D and 3D-AVC, based on H.264/AVC. In addition to color image, depth map is also included to be compressed because of adopting DIBR to generate virtual views.

Adaptive Fast Mode Decision for HEVC Intra Coding
2016 International Conference on Digital Image Computing: Techniques and Applications (DICTA), 2016The latest High Efficiency Video Coding (HEVC) standard offers higher performance than existing video coding standards - up to 50% bit-rate reduction at the equal perceptual quality, but with a significant encoder complexity increase. With regard to intra prediction, a set of 35 intra prediction modes is defined in HEVC to enhance the intra coding ...

Improved fast intra mode decision with reliability refinement
2013 IEEE China Summit and International Conference on Signal and Information Processing, 2013Fast intra mode decision algorithms in video coding are very useful and necessary for practical real-time encoder implementation. It reduces the computational complexity by eliminating unlikely modes from candidate set. However, most of these algorithms may lead to the noticeable quality degradation, especially for the all intra coding scenario.

Fast Intra Mode Decision for HEVC
2016High Efficiency Video Coding (HEVC/H.265), the latest standard in video compression, aims to halve the bitrate while maintaining the same quality or to achieve the same bitrate with an improved quality compared to its predecessor, AVC/H.264. However, the increase in prediction modes in HEVC significantly impacts on the encoder complexity.

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

A fast intra mode decision algorithm for AVS
IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010The AVS video coding standard employs a robust Rate-Distortion Optimization (RDO) technique to improve compression performance. Although RDO technique can achieve better compression efficiency, it also increases tremendous computational complexity. In order to reduce complexity, this paper proposes a fast intra mode decision algorithm for AVS based on ...

Hierarchical fast mode decision algorithm for intra prediction in HEVC
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015This paper proposes a fast intra prediction algorithm for the High Efficiency Video Coding (HEVC). HEVC has 35 modes, such as DC mode, Planar mode, and 33 angular modes for the intra-prediction. To reduce the complexity and to support fast decision for intra prediction, this paper proposes a hierarchical mode decision method (HMD).

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 ...
