JVET-L0672 CE15-related: Separated palette test on top of CE15.2 [Y.-H. Chao, H. Wang, V. Seregin, M. Karczewicz (Qualcomm), Y.-C. Sun, J. An, J. Lou (Alibaba)] [late]

This document reports the results of joint and separated palettes for luma and chroma CUs in inter slice when dual tree is enabled in SPS. The test is performed on top of CE15.2 (L0336). The results reportedly show that:

• For joint palette, 8.6%, and 4.3% BD-rate gains for luma are shown for class F sequences and 15.6%, and 6.5% BD-rate gains for luma are shown for 4:2:0 TGM sequences under RA, and LD configurations, respectively.
• For separated palettes, 8.7%, and 5.2% BD-rate gains for luma are shown for class F sequences and 16.4%, and 8.6% BD-rate gains for luma are shown for 4:2:0 TGM sequences under RA, and LD configurations, respectively.

The proposal showed that the separated palettes shows about 1% gain more the joint palette.

It was agreed to study this in a CE (see notes under JVET-L0427).
