Abstract:
1. An apparatus for estimating motion, comprising: a division unit configured to divide a source picture into a plurality of source regions; an estimation unit configured to calculate an estimated motion vector between a first source region of the plurality of source regions and a first destination region on a destination picture, the first destination region having the highest correlation with the first source region; a weight calculation unit configured to search a plurality of second destination regions on the destination picture, each second destination region being pointed by the estimated motion vector of a second source region adjacent to the first source region, to extract pixel values of each second destination region, to calculate a difference of pixel values between the first source region and each second destination region, and to calculate a first weight based on the difference, the first weight being smaller if the difference is larger; and a filtering unit configured to calculate a motion vector of the first source region by averaging the estimated motion vectors with the first weight.
