Abstract
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.
