Fast rate distortion optimized quantization for HEVC
TL;DR: A RDOQ call removal algorithm is proposed which can effectively remove the redundant RDO Q calls and thus speed up the RDOZ process and an all-zero block-based R DOQ skip algorithm is developed to skip unnecessary RDOq.
Proceedings ArticleDOI
A low complexity architecture for video coding with overlapped block motion compensation
TL;DR: A new decoder- and encoder-friendly architecture for inter prediction with OBMC is proposed and preliminary experimental results that point to coding efficiency gains over the BMC architecture of H.264/MPEG-4 AVC are shown.

Implicit Geometry Partition for Point Cloud Compression
Xiang Zhang,Wen Gao,Shan Liu +2 more
TL;DR: This work proposes a new geometry partition and coding scheme that brings in and harmonizes the asymmetric kd-tree like concept with the symmetric OT-based geometry coding framework, and enables asymmetric bounding boxes that can better fit the shape of 3D scenes.
Journal ArticleDOI
Joint Chroma Subsampling and Distortion-Minimization-Based Luma Modification for RGB Color Images With Application
TL;DR: The experimental results demonstrate that the proposed hybrid method has substantial quality improvement, in terms of the CPSNR quality, visual effect, CPSNR-bitrate trade-off, and Bjøntegaard delta PSNR performance, of the reconstructed RGB images when compared with existing chroma subsampling schemes.

Dealing With User Heterogeneity in P2P Multi-Party Video Conferencing: Layered Distribution Versus Partitioned Simulcast
Eymen Kurdoglu,Yong Liu,Yao Wang +2 more
TL;DR: This paper shows any multicast tree is equivalent to a collection of 1-hop and 2-hop trees, under user uplink-downlink capacity constraints, and reveals that the packet overlay hop count can be limited to two without sacrificing the achievable rate performance.
