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

Abstract: The invention concerns a method for decoding at least one data stream (STR) representative of a multi-view video, comprising at least coded data representative of at least one sub-image, comprising texture data (text0, text1) and depth data (dpth0, dpth1) associated with said texture data, said sub-image (Im0, Im1) comprising at least one zone, referred to as the useful zone (51), intended to be used for generating at least one image of at least one view. An indicator is decoded, indicating whether the sub-image (Im0, Im1) is coded according to a first method or according to a second method. When the indicator indicates that the sub-image is coded according to the first method, a binary map is decoded indicating for at least one pixel of the sub-image whether or not said pixel belongs to the useful zone (51). The texture data and the depth data of the sub-image are decoded, when the indicator indicates that the sub-image (Im0, Im1) is coded according to the second method, the depth data of said sub-image (Im0, Im1) for the pixels situated outside the useful zone (51) comprising a decoded depth value.
