  A quantitative analysis of post-VVC luma and chroma intra tools is presented,
focusing on their statistical behaviors, in terms of block selection rate under
different conditions. The aim is to provide insights to the standardization
community, offering a clearer understanding of interactions between tools and
assisting in the design of an optimal combination of these novel tools when the
JVET enters the standardization phase. Specifically, this paper examines the
selection rate of intra tools as function of 1) the version of the ECM, 2)
video resolution, and 3) video bitrate. Additionally, tests have been conducted
on sequences beyond the JVET CTC database. The statistics show several trends
and interactions, with various strength, between coding tools of both luma and
chroma.
