Person identification process for police force, involves transforming numeric fingerprint image by algorithmic treatment into rectified/corrected image, and detecting characteristic points of fingerprint in corrected image

摘要

The process involves transforming a numeric fingerprint image by an algorithmic treatment into a numerically rectified/corrected image with a level of distortion to a preset threshold when a fingerprint (E) is on a curved surface. The characteristic points of the fingerprint are detected in the corrected image. The current numerical information of the points is compared with numerical information in a bank (17) of information.
