To pinpoint a specific person from two or more individuals per image stored in a database, the order of importance of all individuals in the image must be analyzed. An algorithm is proposed that can be used to automatically analyze the order of importance on the basis of face size and the placement of a face within an image. The relative values among the major person and the others are also calculated. The proposed algorithm includes four steps: detection of faces, acquisition of composition information, selection of the major person, and judgment of order of importance. Tests on 100 images suggest that the proposed algorithm is suitable for analyzing the order of importance of individuals per image.
