The Joint Collaborative Team on Video Coding (jct-vc) of itu-t wp3/16 and iso/iec jtc 1/sc 29/wg 11 held its second meeting during 21-28 July, 2010 at the itu-t premises in Geneva, ch

5.4TE1: Decoder-side motion derivation

A summary report on this topic is found in JCTVC-B029.

JCTVC-B026 [S. Klomp, M. Munderloh, J. Ostermann (Leibniz Univ. Hannover)] Decoder-side motion estimation with modified reference list

This proposal relates to improving compression by performing additional motion estimation at the decoder. As only already decoded data is used, no additional data is transmitted.

This document gives an update of the results presented in Doc. M16570 on the performance of decoder-side motion estimation (DSME) with new test sequences. A dense motion vector field is estimated which reduces the rate by 6.9% in average compared to the H.264/AVC anchors at the same quality.

Used JM 16.2, with conventional MB size.

Remark: Is the dense motion vector field useful? To be studied – a matter of complexity.
