This Motion vectors of depth-maps in multiview and free-viewpoint videos exhibit strongspatial as well as inter-componentclustering tendency. In thispaper, we present a schemethat encodes the motion vector information at the frame level to efficiently exploit thesecorrelations. It arranges the motion vectors ofall the macroblocks of a frame into a 3Dvolume by considering that the horizontal (x-axis) and vertical (y-axis) displacementcomponents belong to adjacent planes (p-axis). Information about the positions ofmacroblocks of identical coding mode is then extracted into different bitmaps. Theproposed scheme first compresses the multidimensional bitmaps of macroblock modeinformation and then encodes only thenon-zero components of motion vectors.
