DEVICE AND METHOD FOR IMAGE COLLATION, PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To improve collation precision. SOLUTION: An image processing means 10 outputs 1st images before and after contraction processing in order. A converting means 20 repeatedly perform at least one of a translation process and a rotating process for a 2nd image by a fixed quantity. A collating means 30 compares the 1st images before and after the contraction processing with the 2nd image to find consistency 403. An arithmetic means 40 finds a mean consistency 404 as the mean value of consistency 403. A maximum consistency extracting means 50 finds the maximum consistency 405 among mean consistency 404. A decision means 60 decides that the 1st images and 2nd image are identical when the maximum consistency 405 is larger than a threshold.
