SUBJECT COLLATION DEVICE, SUBJECT COLLECTION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To highly accurately collate subjects even when the subject temporarily disappears from a camera visual field.SOLUTION: A subject collation device 1 includes: a tentative correspondence setting part 16; a tentative correspondence classification part 17; and a collation part 18. The tentative setting part 16 sets tentative correspondence between a subject which has appeared in a video and a subject which has disappeared from the video before the timing in which the subject has appeared. The tentative correspondence classification part 17 classifies the tentative correspondence set by the tentative correspondence setting part 16 into a plurality of classes by using the position information of the subject in the video. The collation part 18 collates the subject which has appeared with the subject which has disappeared on the basis of the classification result by the tentative correspondence classification part 17.
