Claim Text:
1. A method for processing a reference picture, comprising: i) performing motion estimation on an original picture to be encoded, based on a reconstructed reference picture, and a processed reference picture estimate to provide motion model parameters; ii) further processing the motion estimated picture to obtain a further processed reference picture estimate; and iterating the motion estimation and the further processing to provide a processed reference picture, wherein: the reconstructed reference picture is divided into a plurality of regions, the performing of the motion estimation provides motion model parameters for the plurality of regions, and for at least one region of the reconstructed reference picture in the plurality of regions, the performing of the motion estimation comprises applying a plurality of motion models to the at least one region of the reconstructed reference picture to provide motion model parameters associated with the at least one region of the reconstructed reference picture, wherein each motion model among the plurality of motion models is applied to the at least one region of the reconstructed reference picture separately, the motion model parameters associated with the at least one region being an average or weighted average of motion model parameters provided by applying each of the plurality of motion models to the at least one region of the reconstructed reference picture separately, wherein the applying a plurality of motion models to the at least one region of the reconstructed reference picture comprises: applying a first motion model on the at least one region to generate a first set of motion model parameters; and applying a second motion model on the at least one region to generate a second set of motion model parameters, wherein the motion model parameters associated with the at least one region is obtained by an average or a weighted average of the first set of motion model parameters with the second set of motion model parameters.
