Method For Constructing A Depth Image From A Multiview Video, Method For Decoding A Data Stream Representative Of A Multiview Video, Encoding Method, Devices, System, Terminal Equipment, Signal And Computer Programs Corresponding Thereto

Abstract: The invention relates to a method for constructing a depth image associated with a view from a multiview video, called current view, based on a data stream (FD) representative of said video, said stream comprising information representative of the motion vectors of a texture image associated with said current view with respect to at least one reference texture image (TR), said texture image having been divided into blocks, characterized in that said method comprises: obtaining (70) said motion vectors based on information encoded in the stream; when at least one motion vector (MV) has been obtained for at least one block, called current block, of the texture image, motion-compensating (76) a block (BPc) of the depth image, collocated with the current block, based on said at least one motion vector (MV) and on at least one available reference depth image (PR), said reference depth image (PR) being associated with the same view as said reference texture image (TR).
