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.

摘要： There are provided encoders, decoders and corresponding encoding and decoding methods. A reduced resolution update based video encoder for encoding video data divisible into macroblocks includes a memory device, a downsampler, INTRA coding means, an encoder, a decoder, and an upsampler. The memory device is for storing reduced resolution neighboring pixels. The downsampler is for downsampling a full resolution macroblock to obtain a reduced resolution macroblock. The INTRA coding means is for performing INTRA prediction for the reduced resolution macroblock using the stored reduced resolution neighboring pixels. The encoder is for encoding residual data for the reduced resolution macroblock. The decoder is for decoding the residual data for the reduced resolution macroblock to form a reconstructed low resolution INTRA coded macroblock. The upsampler is for upsampling the reconstructed low resolution INTRA coded macroblock to form a full resolution INTRA coded macroblock. The memory device is further for storing a right column and a bottom row of the reconstructed low resolution INTRA coded macroblock.

摘要： There are provided methods and apparatus for motion skip mode with multiple inter-view reference pictures. An apparatus includes an encoder for encoding an image block relating to multi-view video content by performing a selection, for the image block, of at least one of an inter-view reference picture list from a set of inter-view reference picture lists, an inter-view reference picture from among a set of inter-view reference pictures, and a disparity vector from among a set of disparity vectors corresponding to the inter-view reference picture. The encoder extracts motion information for the image block based on at least one of the inter-view reference picture list, the inter-view reference picture, and disparity vector.
