Abstract
Template based derivation of intra sub-partitioning (ISP) mode is used to improve coding efficiency of intra predicted coded video blocks. The template is formed from surrounding reconstructed top and left samples. In one embodiment, ISP is performed independently from template based intra mode derivation (TIMD). The derivation of an intra sub-block partition mode is determined from template pixels using a current prediction mode for either an upper or left template. In another embodiment, ISP and TIMD are combined. In a further embodiment, a flag is signaled to communicate template based intra mode derivation and intra sub-block partition usage.
