Fingerprint Mosaicing Using Thin Plate Splines
نویسندگان
چکیده
We discuss a fingerprint mosaicing scheme to construct a composite fingerprint image using multiple impressions of the same finger. The composite image is expected to contain more information (e.g., minutiae) compared to the individual impressions thereby improving matching accuracy. The novelty of the proposed algorithm lies in its ability to account for the elastic deformation present in constituent fingerprints before stitching them. A 2D Thin Plate Spline (TPS) model based on minutiae correspondences between a pair of fingerprint images is used as the interpolant function to pre-distort one image based on its deformation with respect to the other. This aids in the better alignment of the two fingerprints and, consequently, better integration. Experiments conducted on the FVC 2002 DB1 database indicate that mosaicing results in a significant improvement in the matching performance.

Image versus feature mosaicing: A case study in fingerprints
Fingerprint mosaicing entails the reconciliation of information presented by two or more impressions of a finger in order to generate composite information. It can be accomplished by blending these impressions into a single mosaic, or by integrating the feature sets (viz., minutiae information) pertaining to these impressions. In this work, we use Thin-plate Splines (TPS) to model the relative ...
متن کاملA Calibration Model For Fingerprint Sensor Interoperability
Biometric sensor interoperability refers to the ability of a system to compensate for the variability introduced in the biometric data of an individual due to the deployment of different sensors. We demonstrate that a simple non-linear calibration scheme, based on Thin Plate Splines (TPS), is sufficient to facilitate sensor interoperability in the context of fingerprints. In the proposed techni...
متن کاملA Comparison of Thin Plate and Spherical Splines with Multiple Regression
Thin plate and spherical splines are nonparametric methods suitable for spatial data analysis. Thin plate splines acquire efficient practical and high precision solutions in spatial interpolations. Two components in the model fitting is considered: spatial deviations of data and the model roughness. On the other hand, in parametric regression, the relationship between explanatory and response v...
متن کاملFinite Element Thin Plate Splines for Data Mining Applications
Thin plate splines have been used successfully to model curves and surfaces. A new application is in data mining where they are used to model interaction terms. These interaction splines break the \curse of dimensionality" by reducing the high-dimensional nonparametric regression problem to the determination of a set of interdependent surfaces. However, the determination of the corresponding th...
