摘要： Systems and methods for efficiently reformatting video data in regions of video including occlusions are disclosed. In one embodiment, the method includes determining multiple motion vectors that link/relate matching blocks of two reference frames and calculating a measure related to overlap area of the matching blocks in one or both of the reference frames with a block to be constructed in an intermediate frame. The measure related to overlap area takes into account a particular interpolation phase of the frame being constructed in relation to the two reference frames. In one embodiment, a ranking of the measure related to overlap areas is used to classify the block to be constructed according to a degree of occlusion. In another aspect the location of the matching blocks in one or both of the reference frames is used in the classification of the block to be constructed.
