  • Publication number: 20250150600
    Abstract: A method that reorders partitioning candidates or motion vectors based on template matching costs for geometric prediction mode (GPM) is provided. A video coder receives data to be encoded or decoded as a current block of a current picture of a video. The current block is partitioned into first and second partitions by a bisecting line defined by an angle-distance pair. The video coder identifies a list of candidate prediction modes for coding the first and second partitions. The video coder computes a template matching (TM) cost for each candidate prediction mode in the list. The video coder receives or signals a selection of a candidate prediction mode based on an index that is assigned to the selected candidate prediction mode based on the computed TM costs. The video coder reconstructs the current block by using the selected candidate prediction mode to predict the first and second partitions.

  • Publication number: 20250150601
    Abstract: A video coding system that reorders prediction candidates is provided. A video coder receives data for a block of pixels to be encoded or decoded as a current block of a current picture of a video. The video coder identifies possible candidate prediction positions. The video coder computes a cost for each of the identified possible candidate prediction positions. The video coder assigns, based on the computed costs, a reordered index to each of N lowest cost candidate prediction positions from the identified possible candidate prediction positions. The video coder selects a candidate prediction position using the assigned reordered indices, wherein the selection is signaled in or parsed from the bitstream. The video coder encodes or decodes the current block by using the selected candidate prediction position.
