Description

·        The fingerprint algorithm extracts feature from the obtained fingerprint image and displays it with the fingerprint data. Keep comparing and searching for all fingerprints done by operating fingerprint features.

·        Fingerprint processing includes two processes: fingerprint registration process and fingerprint matching process. (Where the matching fingerprint is divided into two comparison fingerprints (1:1) and search fingerprints (1: N).

·        When a fingerprint is registered, a fingerprint is entered for each fingerprint, and the image input is processed twice. Synthesis of modules stored in modules.

·        When the fingerprint is matched, the fingerprint sensor uses the input image of the fingerprint to be verified and then processed as compared to the fingerprint module.

·        (If matching with a specified module, it is called fingerprint comparison mode, IE, 1:1 mode. If matching multiple modules, it is called fingerprint search. IE 1: N mode, the module provides matching results (PASS or FAIL).
