Claim One:
1. An apparatus for reconstructing an occlusion region, comprising: a memory having computer readable instructions stored thereon; and at least one processor configured to execute the computer readable instructions to, receive data corresponding to a motion vector field of a video frame, detect an occlusion region in the motion vector field, the occlusion region corresponding to a portion of the motion vector field not having motion vectors or having inaccurate motion vectors, detect a contour between the detected occlusion region and a non-occlusion region, separate the detected contour into a first contour and a second contour based on motion vectors of blocks included in the detected contour, separate the detected occlusion region into a first occlusion region and a second occlusion region, the first occlusion region adjacent to the first contour, and the second occlusion region adjacent to the second contour, reconstruct motion vectors of the first occlusion region based on motion vectors of the first contour, reconstruct motion vectors of the second occlusion region based on motion vectors of the second contour, set the detected occlusion region to the first occlusion region, and convert blocks included in the first occlusion region into the second occlusion region, such that a sum of field discrepancy (FD) values of blocks included in the detected occlusion region decreases or remains unchanged, an FD value of at least one of block in the detected occlusion region is based on a number of neighboring blocks which are included in a different occlusion region from the occlusion region of the at least one block, wherein the FD value of the at least one block is the number of blocks neighboring in four directions, which are included in different occlusion region of the at least one block.
