1. A method of identifying regions of an image requiring motion vector processing, comprising: generating a set of candidate interpolated motion vectors for an interpolation phase of an image to be used for an analyzed phase; selecting an interpolated motion vector from the set of candidate interpolated motion vectors; selecting a first block in a first phase corresponding to a first end of the interpolated motion vector; identifying a second block in the second phase corresponding to a second end of the interpolated motion vector; comparing a first phase motion vector of the first block to a second phase motion vector of the first block to determine if the first block is confirmed; comparing a first phase motion vector of the second block to a second phase motion vector of the second block to determine if the second block is confirmed; and indicating whether the region associated with the interpolated motion vector is an occluded region.
