Solving occlusion in Frame-Rate up-Conversion

Abstract

Tracking motion of moving objects in a video scene by the human eye results in a stationary picture on the retina. However, if the motion is irregular, tracking can be difficult, resulting in the perception of motion blur or motion judder. This is a typical result due to the broadcast of film material. Film is captured at 24 Hz, and by picture repetition displayed at either 50 or 60 Hz. Motion judder can be eliminated at the receiver end by temporally correcting for the motion. Although this significantly improves the viewing experience, it can cause picture degradation at the boundaries of moving objects due to improper interpolation in and around occlusion areas. In this paper, we present a solution to the occlusion problem.
