Title:
MULTI-HYPOTHESES MERGE MODE
Document Type and Number:
WIPO Patent Application WO/2018/127188
Kind Code:
A1
Abstract:
A multi-hypotheses motion prediction mode for video coding is provided. Multi-hypotheses motion prediction conveys prediction for motion compensation based on a selection of multiple predictions for motion compensation (hypotheses), which are respectively obtained using motion predictors or MVP selected from a list of candidate motion predictors. When coding a block of pixels, a video coder implementing multi-hypotheses motion prediction selects a first motion predictor and a second motion predictor from a list of candidate motion predictors for the block of pixels. The video coder encodes or decodes a motion prediction code word that identifies the first and second motion predictors. The video coder computes a combined prediction for motion compensation based on first and second sets of pixels that are obtained using the selected first and second motion predictors, respectively. The video coder encodes or decodes the block of pixels by using the combined prediction for motion compensation.
