Abstract

There are provided methods and apparatus for adaptive reference filtering. An apparatus includes an encoder (100) for encoding at least one picture. The encoder (100) performs adaptive filtering of at least one reference picture to respectively obtain at least one filtered reference picture, and predictively codes the at least one picture using the at least one filtered reference picture. The at least one reference picture is a picture wherein at least one sample thereof is used for inter-prediction either of subsequent to the at least one sample being applied to an in-loop filter or in an absence of the at least one sample being applied to an in-loop filter.
