  • High-speed fingerprint feature identification system and method thereof according to triangle classifications
    Patent number: 9064142
    Abstract: A fingerprint feature identification system and method utilizes multiple feature points on a fingerprint to build feature triangles. Each of the feature triangles are classified as one of predetermined triangle classifications according to geometric data thereof. Every new feature triangle built from a new fingerprint is classified first and then compared with its geometric data to multiple filed feature triangles with the same triangle classification to shorten overall comparison duration.
