Abstract

A method and an apparatus for processing occlusions in motion estimation are described. For processing an occlusion in a forward motion field (FMF t-1/t ) of a second frame (t-1) relative to a first frame (t) the forward motion field (FMF t-1/t ) of the second frame (t-1) relative to the first frame (t) is determined with a motion estimator (22). Then an area (9) in the second frame (t-1) that is occluded in the first frame (t) is identified (13) with an occlusion identifier (24). Finally, a motion corrector (25) determines a corrected forward motion field (CFMF t-1/t ) by filling the forward motion field (FMF t-1/t ) in the identified area (9) in the second frame (t-1) using motion vectors of a previous backward motion field (BMF t-1/t-2 ) of the second frame (t-1) relative to a previous third frame (t-2).
