JVET-B0047 Non Square TU Partitioning [K. Rapaka, J. Chen, L. Zhang, W.-J. Chien, M. Karczewicz (Qualcomm)] [late]

Chaired by J. Boyce.

This contribution proposes non-square TU partitioning for intra and inter prediction modes. Two partition types (2NxN and Nx2N) are added for intra mode. For non-square partitions, a binary split is allowed at the root level (level 0) for intra and inter prediction modes. Further TU splitting processing follows the HEVC mechanism. It is reported that the proposed method provides 1.5%, 1.0%, 0.7%, 0.8% BD-rate saving for AI, RA, LDB and LDP configurations respectively over HM 16.6.

Results are compared with HM 16.6 rather than JEM 1.0. It was not tested vs QTBT.

The minimum TU size is 4x8.

Experimental results vs. the JEM are requested.

Decision (SW): Make SW available in experimental SVN branch of JEM software. Include in the EE document for testing.
