A matching apparatus and method compares a set of feature points of two objects projected to an N-dimensional space and determines the similarity between the objects and includes mapping the set to a one-dimensional space, creating a set of pairs of a feature point of first object that is the most approximate to a feature point of second object, partly extracting the pairs in small order of the pair distance from the set of the pairs of the feature points and creating a partial set of the pairs of the feature points, calculating a rating-scale of the pair belonging to the partial set of the pair of the feature points, and determining the similarity between the first object and the second object on the basis of an average value of the distance.

Matching apparatus, image search system, and histogram approximate restoring unit, and matching method, image search method, and histogram approximate restoring method

A matching technology for determining the similarity between two objects at high velocity with high precision. The matching method for comparing a set of feature points of two objects projected to an N-dimensional space and determining the similarity between the two objects, includes a mapping step of mapping the set to a one-dimensional space, a pairing step of creating a set of pairs of a feature point of first object that is the most approximate to a feature point of second object, a partial-set creating step of partly extracting the pairs in small order of the pair distance from the set of the pairs of the feature points and creating a partial set of the pairs of the feature points, an average-value calculating step, and a determining step of determining the similarity on the basis of an average value of the distance.
