Abstract

Systems, methods, and computer-readable media are provided for updating a history-based motion vector table. In some examples, a method may include obtaining one or more blocks of video data; determining a first motion vector derived from a first control point of a block of the one or more blocks, the block being encoded using an affine motion pattern; determining a second motion vector derived from a second control point of the block; estimating a third motion vector for a predetermined position within the block based on the first motion vector and the second motion vector; and populating a history-based motion vector predictor (HMVP) table with the third motion vector.

Description

technical field [0001] In general, the present disclosure relates to video encoding and compression, and more specifically, the present disclosure relates to history-based motion vector prediction. Background technique [0002] Many devices and systems allow video data to be processed and output for consumption. Digital video data includes large volumes of data to meet the needs of consumers and video providers. For example, consumers of video data expect the highest quality video with high fidelity, resolution, frame rate, etc. As a result, the large amount of video data required to meet these demands places a burden on communication networks and devices that process and store the video data. [0003] Various video encoding techniques can be used to compress video data. Video encoding is performed according to one or more video encoding standards. For example, video coding standards include Elementary Video Coding (EVC), High Efficiency Video Coding (HEVC), Advanced Vid...
