A New Fingerprint Orientation Model and Its Applications
Date and time:
Venue: 10.08.04
Chair: Xiaodong Li
Abstract:
We propose a novel analytical model to represent fingerprint orientation fields.
The new model consists of two trigonometrical polynomials based on the
two-dimensional (2D) Fourier Expansion functions which is
different from the existing polynomial model. It provides a comprehensive
method, for the first time to our knowledge, that can
accommodate both the inherent global and local features smoothly without
patching descriptions.
In addition to its superior performance in describing fingerprint orientation fields, the analytical model is also shown to be useful in inferring fingerprint singularities. Its other application has demonstrated very promising results in fingerprint classification. The proposed model has provided a framework with a new angle to look at the feature extraction and representation of fingerprints. Our experiment has validated the proposed framework.
