Abstract
An image processing device includes a storage unit that stores dictionary information; a generating unit that extracts, from an input image, a plurality of characteristic point candidates, and generates a plurality of combinations that each include a plurality of characteristic point candidates; a removing unit that removes, for each of the combinations, at least one characteristic point candidate based on at least one of the dictionary information and information obtained by analyzing the input image; and a determining unit that acquires, for each of the combinations, results of matching the dictionary information with the combination of which the at least one characteristic point candidate has been removed, selects a combination of characteristic point candidates based on the acquired matching results, and determines, as the characteristic points, the plurality of characteristic point candidates included in the selected combination.
