1. A computer-implemented method for performing occlusion detection in frame rate up-conversion of video data including a sequence of image frames, comprising:
determining, by a video processor, whether a target block of a target frame is a potential occlusion block based on at least one of motion vector information or distortion metric information associated with the target block, wherein the target frame is to be generated and interpolated into the sequence of image frames; and
responsive to the target block being the potential occlusion block, detecting, by the video processor, an occlusion type of the target block; and
generating, by the video processor, the target block by performing a motion compensation method adaptively selected based on the occlusion type of the target block.
