摘要
An obj ect of the present invention is to appropriately segment fingerprint regions from a ten-print card, reduce an error of imprinting position or an error of finger position specification, and improve fingerprint matching accuracy. Specifically, a system, which computer processes a tenprint card where fingerprint images are imprinted, provides a processing mechanism which automatically crops or segments respective fingerprint images on the tenprint card. In particular, the system provides: a processing mechanism which appropriately crops or segments a slap print image, even if a fingerprint image of slap prints does not fit in a predetermined frame or even if noise other than fingerprints to be cropped or segmented is present within a frame of a four-finger slap, by using a result of matching with rolled prints; and a processing mechanism which checks a correspondence relationship between the rolled prints and the plane prints, assesses a finger position, and detects an error of imprinting position.
