A computationally scalable fast intra coding scheme for HEVC video encoder
TL;DR: An intra prediction scheme with seven predefined levels of complexity is presented that provides coding for various power budgets and devices with various capabilities and imposes almost no computational overhead since it utilizes the existing internal operators of HEVC.

TL;DR: The subjective quality of the proposal is evaluated extensively and the results show that the proposed method achieves similar visual quality as H.264/AVC High Profile anchors with around 50% and 35% bit rate reduction for low delay and random-access experiments respectively at high definition sequences.

Compression of computer generated phase-shifting hologram sequence using AVC and HEVC
TL;DR: This paper proposes to use HEVC for compressing the phase-shifting digital hologram sequences (PSDHS), and results show that AVC and HEVC are efficient to compress PSDHS, with HEVC giving better performance.

Data-Driven Rate Control for Rate-Distortion Optimization in HEVC Based on Simplified Effective Initial QP Learning
TL;DR: The proposed LIQP method outperforms the latest HM-16.14 by achieving significant gains on R-D performance, quality smoothness, and more stable buffer occupancy control, and can also work well for scene change cases.

Occupancy-Map-Based Rate Distortion Optimization and Partition for Video-Based Point Cloud Compression
TL;DR: This work proposes an occupancy-map-based rate distortion optimization and partition to divide the occupied pixels from different patches and the unoccupied pixels into different prediction units (PUs) and shows that the algorithms can individually contribute significant performance improvements compared with the V-PCC.
