JVET-C0002 JVET AHG report: JEM algorithm description editing (AHG2) [J. Chen, E. Alshina, J. Boyce]

This document reports the work of the JVET ad hoc group on JEM algorithm description editing (AHG2) between the 2nd JVET meeting at San Diego, USA (20–26 February 2016) and the 3rd Meeting at Geneva, Switzerland (26 May – 1 June 2016).

During the editing period, on top of JVET-A1001 Algorithm Description of Joint Exploration Test Model 1, the editorial team worked on the following three aspects to produce the final version of JVET-B1001 Algorithm Description of Joint Exploration Test Model 2.

1. Integrate the following normative adoptions of the 2nd JVET meeting

• JVET-B0038: Harmonization of AFFINE, OBMC and DBF
• JVET-B0051: Non-MPM intra mode coding
• JVET-B0058: 1/16 pel motion vector storage accuracy

1. Add brief encoding logic description of the following JEM2 coding tools

• Locally adaptive motion vector resolution (AMVR)
• Overlapped block motion compensation (OBMC)
• Local illumination compensation (LIC)
• Mode dependent non-separable secondary transforms
• Adaptive loop filter (ALF)

1. Overall text refinement and quality improvement

Currently the document contains the algorithm description as well as encoding logic description for all the new coding features in JEM2.0.

The AHG recommended to:

• Continue to edit the Algorithm Description of Joint Exploration Test Model document to ensure that all agreed elements of JEM are described
• Continue to improve the editorial quality of the Algorithm Description of Joint Exploration Test Model document.
