CE5: Maximum Palette Size and Maximum Palette Predictor Size (6) CE5 summary and general discussion (1)

13.0.0.1.1.1.1.1.107JCTVC-S0025 CE5: Summary report of core experiment 5 on investigation of maximum palette size and maximum palette predictor size [R. Joshi, X. Xiu (CE coordinators)]
This document summarizes the Core Experiment 5 (CE5) on investigation of maximum palette size and maximum palette predictor size. The BD-rate impact of changing the maximum palette size and maximum palette predictor size was studied.
In SCM-2.0, the maximum palette size is 31 and maximum palette predictor size is 64. In the 18th JCT-VC meeting in Sapporo, core Experiment 5 (CE5) was formed to investigate the impact of varying the maximum palette size and the maximum palette predictor size on BD-rate. Both increase and decrease in palette size and palette predictor size was considered. This contribution describes test conditions, test results, and comparisons.
All tests were conducted under SCM-2.0 common test conditions, which enabled full frame intra block copy (FF-IBC) as anchor.
Since palette is an intra tool, BD-results are presented and compared only for All-Intra (AI) lossy configuration. The trend for RA and LD-B configurations is similar to what is seen for AI configuration.
