JVET-K0352 CE4-related: Encoder optimization on top of CE 4.2.13 [J. Ye, X. Li, S. Liu (Tencent)]

This contribution proposes an encoder optimization algorithm on top of CE 4.2.13. The proposed method reports 0.30% and 0.29% luma coding gain compare to CE 4.2.13 Test A in RA and LDB configuration on VTM with 1–2% encoding time increase.

It is claimed that about 0.15% coding gain if it is applied to VTM.

Recommendation: Consider using this encoder optimization in CE on merge related tests, and in the anchors as well.

Decision (SW/CTC both VTM and BMS): Adopt JVET-K0352 encoder optimization

Note that the same encoder optimization is used in JVET-K0198. Software will be provided by the JVET-K0352 contribution.
