JCTVC-B079 [S. Li, L. Yu (Zhejiang Univ.)] Second order prediction

This contribution proposes a method named Second Order Prediction (SOP) to exploit remaining spatial correlation of motion-compensated prediction residue by using intra prediction. The experiments results reportedly show that SOP can achieve an average 1.5% BD bit rate saving among B and C class sequence under constraint set 1 test conditions and 2% for constraint set 2.

Roughly 30% encoding time increased – testing 2 intra prediction modes (vertical and DC) during the motion search and then 9 modes after choosing a candidate motion vector.
