JM-101B features
- The feature extracted by the fingerprint algorithm from the acquired fingerprint image represents the information of the fingerprint. Fingerprint storage, comparison, and search are all done by manipulating fingerprint features.
- Fingerprint processing consists of two processes: fingerprint login process and fingerprint matching process [where fingerprint matching is divided into fingerprint comparison (1:1) and fingerprint search (1:N)].
- When the fingerprint is registered, each fingerprint is entered twice, the recorded image is processed twice, and the composite template is stored in the module.
- When the fingerprint is matched, the fingerprint image is entered and the fingerprint image is verified, processed, and then matched with the fingerprint template in the module. If the template is matched with a template specified in the module, it is called a fingerprint comparison method, that is, 1:1. Mode; if matching with multiple templates, called fingerprint search mode, ie 1:N mode), the m

- When the fingerprint is matched, the fingerprint image is entered and the fingerprint image is verified, processed, and then matched with the fingerprint template in the module. If the template is matched with a template specified in the module, it is called a fingerprint comparison method, that is, 1:1. Mode; if matching with multiple templates, called fingerprint search mode, ie 1:N mode), the module gives the matching result (pass or fail).
