A New Frame Memory Compression Algorithm with DPCM and VLC in a 4×4 Block
TL;DR: Experimental results show that the new FMC algorithm in an H.264 encoder achieves 1.34 dB better image quality than a previous MHT-based FMC for HD-size sequences.

Complexity Control in the HEVC Intracoding for Industrial Video Applications
TL;DR: A feedback-based error elimination scheme removes the complexity error during the encoding process and the rate-distortion performance and complexity control accuracy of the proposed method are superior to those of the state-of-the-art methods.

Zhenyu Wei,King Ngi Ngan +1 more
TL;DR: A simple and accurate bit estimation model is proposed and used in RDO scheme and it is proved that the proposed fast RDO algorithm can reduce about 60% total encoding time and save about 76% computation time of RDO module with little degradation in coding performance.

360° Video Coding Based on Projection Format Adaptation and Spherical Neighboring Relationship
TL;DR: This paper describes a 360° video coding scheme submitted in response to the joint call for proposal on video compression for capability beyond HEVC issued by ITU-T SG16 Q.6 (VCEG) and ISO/IEC JTC1/SC29/WG11 (MPEG) in October 2017, and achieves average bit rate savings of 33.9% over the HM and joint exploration model anchors.

Fast HEVC screen content coding by skipping unnecessary checking of intra block copy mode based on CU activity and gradient
TL;DR: This work proposes to skip the unnecessary IntraBC mode checking based on the activity and gradient within the coding unit (CU), which means the increased encoding time compared with the conventional HEVC is reduced and the coding efficiency can still be maintained.
