Singular Points Analysis in Fingerprints Based on Topological Structure and Orientation Field
Abstract. As an important feature of fingerprints, singular points (includingcores and deltas) not only represent the local ridge pattern characteristics, but also determine the to...

Curvature and Singularity Driven Diffusion for Oriented Pattern Enhancement with Singular Points
Oriented patterns, e.g. fingerprints, consist of smoothly varying flow-like patterns, together with important singular points (i.e. cores and deltas) where the orientation change...

From Template to Image: Reconstructing Fingerprints from Minutiae Points
—Most fingerprint-based biometric systems store the minutiae template of a user in the database. It has been traditionally assumed that the minutiae template of a user does not r...

Fingerprint Classification Based on Extraction and Analysis of Singularities and Pseudoridges
In this paper, we introduce a new approach to fingerprint classification based on both singularities and traced pseudoridge analysis. Since noise exists in most of the fingerprint...

Fingerprint orientation analysis with topological modeling
This paper proposes to characterize the fingerprint orientation using a novel topological representation, which transforms the orientation field into a map composed of a set of ...
