JVET-X0099 Non-EE2: Extension of TIMD to intra chroma coding [Y. Wang, K. Zhang, L. Zhang, H. Liu (Bytedance)]

This contribution presents to extend template-based intra mode derivation to intra chroma coding, known as TIMD-Chroma. Compared to ECM-2.0, simulation results of the proposed method are reported as below:

AI: {-0.09%, -0.16%, -0.14%; 101%, 104%};

RA: {-0.05%, -0.13%, -0.04%; 101%, 100%}.

No good tradeoff was evident for complexity vs. compression benefit. No action was thus taken on this at this point.
