GEO with MMVD
Abstract
This contribution proposes to harmonize GEO with MMVD such that MVD can be applied to derive MV of a GEO partition. The proposed method first determines base MV using current GEO MV calculation, then computes MVD for each base MV following method like MVD calculation for MMVD. Simulation results show the proposed method has BD-rate of approximately -0.25%, -0.36%, -0.49% for RA, and -0.51%, -0.66%, -0.97% for LB, respectively, compared to VTM-8.0 anchor.
JVET-R0282 GEO with MMVD [K. Panusopone, S. Hong, L. Wang (Nokia)]
This contribution proposes to harmonize GEO with MMVD such that MVD can be applied to derive MV of a GEO partition. The proposed method first determines base MV using current GEO MV calculation, then computes MVD for each base MV following method like MVD calculation for MMVD. Simulation results show the proposed method has BD-rate of approximately -0.25%, -0.36%, -0.49% for RA, and -0.51%, -0.66%, -0.97% for LB, respectively, compared to VTM-8.0 anchor.
Encoding time increase is roughly 30% for RA, and over 30% for LB. This is not an attractive tradeoff.
