<P>PROBLEM TO BE SOLVED: To provide a data classifier capable of classifying face image data by photographing conditions or the property of an object. <P>SOLUTION: A map generation part 21 temporarily decides clusters to which the respective prototypes of a map belong, successively selects the respective prototypes as the prototype under consideration to be an object to be classified into the cluster, computes a measure between at least one prototype belonging to the respective clusters and the prototype under consideration, and changes the cluster to which the prototype under consideration should belong on the basis of the computed measure as needed. By repeating the processings, for the face image data for which a face of a person is photographed, a self-organized map divided in the clusters defined by the photographing state and the property of the object is obtained. <P>COPYRIGHT: (C)2004,JPO |
