Methods and apparatus for adaptive reference filtering

摘要

There are provided methods and apparatus for adaptive reference filtering. An apparatus includes an encoder for encoding at least one picture. The encoder 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.

1. An apparatus, comprising:
an encoder configured to encode at least one picture in a current view in a multi-view video, wherein said encoder is configured to perform adaptive filtering of at least one reference picture in another view in the multi-view video to respectively obtain at least one filtered reference picture, and to predictively code the at least one picture using the at least one filtered reference picture, and wherein pixels of the at least one picture are classified into different groups in response to disparity information between the at least one picture and the at least one reference picture, and each of the different groups is associated with one of a plurality of filters, the classification being responsive to disparity ranges, the at least one reference picture being 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.
