PERIODIC PATTERN HANDLING BY DISPLACEMENT VECTORS COMPARISON

摘要

Provided are a method and an apparatus for correcting an erroneous displacement vector in an image. The apparatus includes: an image divider configured to divide an image into a plurality of segments according to displacement vectors of pixels of the image, each of the plurality of segments corresponding to a representative displacement vector; an erroneous displacement vector detector configured to determine whether a representative displacement vector of a current comparing segment, from among the plurality of segments, is erroneous due to periodicity by comparing the representative displacement vector of the current comparing segment with a representative displacement vector of a reference segment, from among the plurality of segments; and a displacement vector corrector configured to correct the representative displacement vector of the current comparing segment in response to the erroneous displacement vector detector determining that the representative displacement vector of the current comparing segment is erroneous.
