Title:
METHOD AND APPARATUS FOR CREATING A DISOCCLUSION MAP USED FOR CODING A THREE-DIMENSIONAL VIDEO
Document Type and Number:
WIPO Patent Application WO/2013/022401
Kind Code:
A3
Abstract:
It is presented a method for creating a disocclusion map used for coding a three- dimensional, 3D, video, the method comprises receiving (800) a pixel-based disocclusion map in which pixels are marked either as disoccluded or not. A block- based disocclusion map is derived (802) based on the pixel-based disocclusion map. An area of the block-based disocclusion map that has been marked as disoccluded is extended (804). It is also presented an encoder (30), a decoder (32) and a system for creating the disocclusion map.
