Claim Text:
1. A method, performed by a processor in a view synthesis apparatus, for creating a disocclusion map used for coding a three-dimensional (3D) video, the method comprising: receiving, by the processor, from a disocclusion detection system, a pixel-based disocclusion map in which pixels are marked either as disoccluded or not; deriving, by the processor, a block-based disocclusion map based on the pixel-based disocclusion map; extending, by the processor, an area of the derived block-based disocclusion map, which has been marked as disoccluded, temporally by keeping said area marked as disoccluded for a particular duration even if said area is no longer disoccluded; and coding, by the processor, the three-dimensional (3D) video by using the extended block-based disocclusion map.
