Fingerprint Image Enhancement Based on Second Directional Derivative of the Digital Image
<p/> <p>This paper presents a novel approach of fingerprint image enhancement that relies on detecting the fingerprint ridges as image regions where the second directional derivative of the digital image is positive. A facet model is used in order to approximate the derivatives at each i...
