Sample Adaptive Offset in the HEVC Standard
Chih-Ming Fu,Elena Alshina,Alexander Alshin,Yu-Wen Huang,Chen Ching-Yeh,Chia-Yang Tsai,Hsu Chih-Wei,Shaw-Min Lei,Jeong-Hoon Park,Woo-Jin Han +9 more
TL;DR: This paper provides a technical overview of a newly added in-loop filtering technique, sample adaptive offset (SAO), in High Efficiency Video Coding (HEVC), to reduce sample distortion by first classifying reconstructed samples into different categories, obtaining an offset for each category, and then adding the offset to each sample of the category.

Improved Video Compression Efficiency Through Flexible Unit Representation and Corresponding Extension of Coding Tools
Woo-Jin Han,Min Jung-Hye,Il-Koo Kim,Elena Alshina,Alexander Alshin,Tammy Lee,Jianle Chen,Vadim Seregin,Sun-Il Lee,Yoonmi Hong,Min-Su Cheon,Nikolay Shlyakhov,Ken McCann,Thomas Davies,Jeong-Hoon Park +14 more
TL;DR: A novel video compression scheme based on a highly flexible hierarchy of unit representation which includes three block concepts: coding unit (CU), prediction unit (PU), and transform unit (TU), which was a candidate in the competitive phase of the high-efficiency video coding (HEVC) standardization work.

Image encoding method and device, and decoding method and device therefor
TL;DR: In this article, a video decoding method and a video encoding method and apparatus are presented. But they do not consider the difference between the current coding unit and the predicted coding unit.

Motion Compensated Prediction and Interpolation Filter Design in H.265/HEVC
Kemal Ugur,Alexander Alshin,Elena Alshina,Frank Bossen,Woo-Jin Han,Jeong-Hoon Park,Jani Lainema +6 more
TL;DR: The details of the interpolation filter design of the H.265/HEVC interpolation filtering over H.264/AVC are presented and coding efficiency gains are significant for some video sequences and can reach up to 21.7%.
Patent
Method and apparatus for video encoding and method and apparatus for video decoding
TL;DR: In this article, a method and an apparatus for video encoding using bidirectional motion compensation in pixel units and a method for video decoding is described, which is based on one embodiment of the present invention.
