Abstract
An image-registration method, medium, and apparatus obtaining first and second images, generating first and second image pyramids based on the first and second images, respectively, by performing sub-sampling which reduces the length and width of each of the first and second images by half, and determining one of five directions as an optimal movement direction for a current level of the first and second image pyramids based on two images belonging to a corresponding level, updating a motion vector for the current level based on the optimal movement direction for the current level and updating a first image belonging to a level directly below the current level based on the updated motion vector for the current level, wherein the updating comprises updating a motion vector for each of a plurality of levels of the first and second image pyramids in an order from an uppermost level to a lowermost level.
