Abstract
The solid state fingerprint sensors are small in size and can be easily installed on mobile devices. However, the small contact area limits the number of collected minutiae, making the fingerprint matching less reliable. Recently, template synthesis of fingerprints is proposed to augment the available minutiae set during registration. However, this approach is not feasible when two fingerprints are severely distorted. In this paper, we propose a novel way of fingerprint template normalization for distortion removal. Instead of performing expensive processing of the fingerprint images, we suggest that the normalization can be applied to the extracted minutiae using the ridge structure gathered during direct gray scale.
