G06V 40/12
Definition
Diese Klassifikationsstelle umfasst:(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)
Acquisition, pre-processing, feature extraction and
- matching for biometric identification purposes; or
- classification into types; or
- detecting the live character of the finger, i.e. distinguishing from a fake or cadaver finger by using either specialised acquisition arrangements or by image processing.
Pre-processing and feature extraction for the purpose of fingerprint recognition, e.g.:
- denoising/filtering, enhancement, normalisation;
- minutiae extraction;
- ridge properties extraction, such as ridge spatial frequency and ridge orientation.
Examples
Fingerprint representations by ridges (thin and thick lines) and minutiae (ridge endings (1) and (2) and bifurcations (3))
The sets of minutiae extracted from two fingerprint images are matched to establish the person’s identity; the small circles denote matched pairs.

Spezielle Klassifizierungsregeln
Detection of the static pose of the hand or biometrics obtained from hand geometrical arrangement of the fingers, e.g. distance between the finger joints is classified in group G06V 40/10.
Techniques involving multiple biometrics are classified in group G06V 40/70.
