Patent number: 5995642Abstract: A method for automatic fingerprint classification is dependent on the number of core points and the ridge flow direction around the core points. The speed of the classification process is improved by pre-processing the fingerprint image to identify the background blocks and the fingerprint blocks, so that the process only deal with the fingerprint blocks. A block directional image is constructed for the fingerprint blocks. The block directional image is then used to determine the core point(s) of the fingerprint. Based on the number of core point and the trend of the ridge direction around each core point, fingerprints can be classified into 8 classes based on a set of predetermined rules.Type: GrantFiled: June 30, 1997Date of Patent: November 30, 1999Assignee: Aetex Biometric CorporationInventors: Shu-Fang Hsu, Paul-Waie Shew, Pei-Yung Hsiao
