Adaptive Direct Motion Vector Estimation with Simple Decoder-side Refinement
Yusuke Itani, Shun-ichi Sekiguchi · The Journal of The Institute of Image Information and Television Engineers · 2012
We propose a method of combination of explicit and implicit direct vector derivation with Decoder-side ME. First of all, the best candidate is selected with explicit signaling. Then, we search around best candidate with Decoder-side ME. Experimental results show coding gain up to 0.8% BD rate reduction compared to a method based on explicit signaling.
