摘要： Systems and methods are disclosed for improving the prediction efficiency for residual prediction using motion compensated residual prediction (MCRP). Exemplary residual prediction techniques employ motion compensated prediction and processed residual reference pictures. Further disclosed herein are systems and methods for generating residual reference pictures. These pictures can be generated adaptively with or without considering in-loop filtering effects. Exemplary de-noising filter designs are also described for enhancing the quality of residual reference pictures, and compression methods are described for reducing the storage size of reference pictures. Further disclosed herein are exemplary syntax designs for communicating residuals' motion information.

摘要： Systems and methods are described for video coding using generalized bi-prediction. In an exemplary embodiment, to code a current block of a video in a bitstream, a first reference block is selected from a first reference picture and a second reference block is selected from a second reference picture. Each reference block is associated with a weight, where the weight may be an arbitrary weight ranging, e.g., between 0 and 1. The current block is predicted using a weighted sum of the reference blocks. The weights may be selected from among a plurality of candidate weights. Candidate weights may be signaled in the bitstream or may be derived implicitly based on a template. Candidate weights may be pruned to avoid out-of-range or substantially duplicate candidate weights. Generalized bi-prediction may additionally be used in frame rate up conversion.
