Fig. 1From: Identification performance of evidential value estimation for ridge-based biometrics[2] Diagram of the evidential value algorithm (EVA). A fingermark is captured with an imaging device and scaled based on the capture resolution estimation (CRE) to 500 ppi; image features are extracted and classified; resulting after thresholding in the binary decision if this mark is of sufficient evidential value (EV) or not (\(\overline {EV}\))Back to article page
