JCTVC-M0312 Non-SCE1: Inter-layer intra mode prediction [J. Min, E. Alshina (Samsung)]
This contribution presents two methods which exploit base layer intra prediction mode. If Intra modes from the collocated base-layer (CorDir) is angular (2~35), CorDir, CorDir+1, CorDir-1 are set to three MPMs. If CorDir is Planar or DC, intra prediction modes from left and above neighbour (LeftDir and AboveDir) are checked and MPM setting is performed to using CorDir. Both of the proposed methods reportedly provide performance gains of −0.4%, −0.2%, −0.2% for AI 2x test conditions.
The "method 2" tested was simpler, had been proposed before, and had the same gain as the "method 1". Similar to results obtained from SCE1 technique, which is roughly similar.
It was remarked that intra modes in the EL would be decoded incorrectly if BL data is lost.
No action, due to parsing dependency issue.
