JVET-AD0114 Non-EE2: Modification of MV redundancy/similarity check considering LIC during merge candidate list construction [K. Kim, D. Kim, J.-H. Son, J.-S. Kwak (WILUS)]

This contribution proposes the modification of MV redundancy/similarity check procedure considering LIC usage during merge candidate list construction. A condition has been added to check whether the use of LIC is the same when performing MV redundancy/similarity check on the neighbouring blocks with uni-prediction. The modification would allow LIC ON and OFF candidates with similar motion vectors to be included in the merge candidate list, providing an opportunity to selectively apply LIC in CUs using merge mode. Compared with ECM-8.0, the proposed methods achieve -0.03% and -0.04% gain in RA and LDB configurations, respectively, with 99% encoder and 98% decoder run time in LDB configurations of common test condition.

RA: {-0.03%, 0.05%, 0.03%, 100%, 100%}

LDB: {-0.04%, 0.02%, 0.12%, 99%, 98%}

Reason for encoding time reduction not obvious.

Benefit not obvious enough to investigate in EE.
