ABSTRACT:
A human identification apparatus, which can judge for identification of human images even in temporally-distant frames or frames shot with different cameras, judges whether or not persons represented by human images respectively included in different image sequences are the same person, and includes: a walking posture detecting unit which detects first and second walking sequences, each sequence being an image sequence indicating a walking state of respective first and second persons respectively included in the different image sequences; and a walking state estimating unit which estimates a transition state of a walking posture in the periodic walking movement of the first person at a time or in a position different from a time or a position of the walking sequence of the first person; and a judging unit which verifies whether or not the estimated transition state of the walking posture of the first person matches the transition state of the walking posture of the second person, and judges that the first person and the second person are the same person in the case where the transition states match with each other.
