Energy-efficient memory hierarchy for motion and disparity estimation in multiview video coding
TL;DR: Experimental results show that the reference-centered memory hierarchy outperforms the state-of-the-art by providing reduction of up to 71% for external memory energy, 88% on-chip memory static energy, and 65% on -chip memory dynamic energy.

Symmetric line graph transforms for inter predictive video coding
Keng-Shih Lu,Antonio Ortega +1 more
TL;DR: This paper describes the relationship between bisymmetric matrices and the butterfly structure in fast transform algorithms and introduces a new class of transforms called Symmetric Line Graph Transforms (SLGTs), of which the discrete cosine transform (DCT) is one particular case.

Optimal Adaptive Quantization Based on Temporal Distortion Propagation Model for HEVC
TL;DR: The proposed algorithm outperforms several related methods from the state-of-the-art and an in-depth analysis of the algorithm behavior includes, among others, the relative distribution of rates between frames and the control of quantizers dynamic range.

No-reference bitstream-based impairment detection for high efficiency video coding
Glenn Van Wallendael,Nicolas Staelens,Lucjan Janowski,Jan De Cock,Piet Demeester,Rik Van de Walle +5 more
TL;DR: It is shown that impairments on HEVC compressed sequences are more visible compaired to H.264/AVC encoded sequences, and that an impairment detection model designed for H. 264/ AVC could be reused onHEVC, but that caution is advised.

A fast intra mode decision method based on reduction of the number of modes in HEVC standard
TL;DR: The number of the tested modes in RMD is reduced from 35 to 19 in this proposed method, which results indicate 14.2% reduction in the encoding time whereas the R-D specification in general remains unchanged.
