  • Detecting occlusion
    Patent number: 8373796
    Abstract: Common techniques for Motion Compensated Frame Rate Conversion (MC-FRC) suffer from occlusion which, if not taken explicitly into account, causes a visually disturbing artifact known as ‘halo’. To solve this artifact, these regions have to be detected prior to performing interpolation. Several techniques exist to detect occlusion in a frame, but these are based on motion vectors, which are frequently unreliable. The invention relates to a method to detect occlusion by comparing match errors, thereby offering occlusion detection even when the motion vectors are incorrect.
