Methods And Devices For Coding And Decoding A Multi View Video Sequence

Abstract: The invention relates to a method for coding and a method for decoding a coded data stream representing a multi-view video. The coded data stream comprises coded data representing at least one atlas, said at least one atlas corresponding to an image comprising at least one patch, said at least one patch corresponding to a set of pixels extracted from at least one component of a view of the multi-view video, said view not being coded in said coded data stream. The method for decoding particularly comprises decoding, from said coded data stream, said at least one atlas, comprising: decoding said at least one patch, determining, for said at least one decoded patch, whether a transformation, and which transformation, must be applied to said at least one decoded patch, said transformation belonging to the group of transformations comprising at least over-sampling of the patch or a modification of the values of pixels of the patch, and applying the determined transformation to said decoded patch.
