CE15-related: Palette predictor list enhancement
Authors: J. Ye Tencent Xinwei Li Tencent Xiaozhong Xu Tencent Shan Liu Tencent
Abstract
In this contribution, it is proposed to derive the spatial palette predictor from the spatial neighboring blocks’ palette table first. Then combine the spatial palette predictor with HEVC SCC palette predictor. The proposed method reports -0.14%,-0.04%, and -0.04% luma and chroma BD rate changing for AI configuration on class SCC over CE 15.2.
Meeting Notes
JVET-L0451 CE15-related: Palette predictor list enhancement [J. Ye, X. Li, X. Xu, S. Liu (Tencent)] [late]

In this contribution, it is proposed to derive the spatial palette predictor from the spatial neighbouring blocks’ palette table first. Then combine the spatial palette predictor with HEVC SCC palette predictor. The proposed method reports -0.14%, -0.04%, and -0.04% luma and chroma BD rate changing for AI configuration on class SCC over CE 15.2.

Q: does the proposal consider CTU boundary? A: Yes.

The crosschecker commented that it is interesting to investigate the correlation between the current palette and non-adjectent palette. It is good to study this method in the CE.

The BoG recommended to study this in the next CE.
