Non-EE2: CIIP with more combination candidates
Authors: Chuan Zhou vivo Z. Lv vivo Jiaqi Zhang vivo
Abstract
This contribution proposes a new inter and intra combination method to optimize CIIP mode. Firstly, an intra prediction modes list is constructed. Then the prediction samples combined a pair of intra prediction mode in the obtained list and a merge candidate is generated using the weighting factors derived by a linear model-based weighted method, which is the LDL decomposition method same as CCCM. The experimental results are summarized as follows:

JVET-AD0174 On CIIP improvement [C. Zhou, Z. Lv, J. Zhang (vivo)]

This contribution proposes a new inter and intra combination method to optimize CIIP mode. Firstly, an intra prediction modes list is constructed. Then the prediction samples combined a pair of intra prediction mode in the obtained list and a merge candidate is generated using the weighting factors derived by a linear model-based weighted method, which is the LDL decomposition method same as CCCM. The experimental results are summarized as follows:

On top of ECM-8.0

LB : -0.10% (Y), 0.09% (U), 0.32% (V), 10x% (EncT), 10x% (DecT)

RA: -0.04% (Y), 0.03% (U), 0.02% (V), 10x% (EncT), 10x% (DecT)

Compression benefit small, current implementation has increase in encoding run time.

No relevant support by other experts for investigating the proposal in EE. Further study was recommended.
