APPARATUS AND METHOD FOR PROCESSING IMAGE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image processing apparatus for easing the non-facilitation of threshold setting in face image clustering, and for improving face image clustering performance. SOLUTION: The image processing apparatus 1 includes: a sequence creating section configured to create a plurality of sequences in such a manner that one sequence includes consecutive face images of a same person in video image data; a similarity calculating section configured to calculate a first similarity of each pair in a plurality of face image dictionaries created for each sequence and a second similarity of each pair of each face image dictionary and a predetermined plurality of dictionaries; a similarity correcting section configured to correct the calculated and obtained plurality of first similarities by the second similarities; and a face clustering section configured to compare the plurality of first similarities corrected by the similarity correcting section with a predetermined threshold to cluster the plurality of face image dictionaries.
