摘要
There are provided methods and apparatus for adaptive reference filtering of bi-predictive pictures in multi-view coded video. An apparatus includes an encoder (100) for encoding a current picture as a bi-predictive picture. The encoder (100) performs adaptive filtering of at least one reference picture to respectively obtain at least one filtered reference picture, and bi-predictively codes the current 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 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. Reference filter coefficients for the adaptive filtering are determined responsive to at least one of luma values and chroma values of pixels grouped based on at least one of depth and disparity and motion.
