Generalized Multi-Hypothesis Prediction System and Method for Video Coding

摘要

Systems and methods for video coding using generalized amount prediction are described. In an exemplary embodiment, a first reference block is selected from a first reference picture and a second reference block is selected from a second reference picture, in order to code the current block of video into the bitstream. Each reference block is associated with a weight, where the weight may be any weight ranging, for example, between zero and one. The current block is predicted using the weighted sum of the reference blocks. The weights may be selected from among a plurality of candidate weights. The candidate weights may be signaled in the bitstream or implicitly derived based on the template. The candidate weights may be pruned to avoid candidate weights that are out of range or substantially redundant. The generalized amount prediction may additionally be used in frame-rate up-conversion.
