To evaluate the performance of fingerprint-image matching algorithms on large datasets, a receiver operating characteristic (ROC) curve is applied. From the operational perspective, the true accept… (More)

FFT-based Alignment of 2d Closed Curves with Application to Elastic Shape Analysis

• Günay Dogan, Javier Bernal, Charles R. Hagwood
• 2015

For many shape analysis problems in computer vision and scientific imaging (e.g., computational anatomy, morphological cytometry), the ability to align two closed curves in the plane is crucial. If… (More)

Software Testing: Protocol Comparison

• James Yen, David Banks, Peter C. Black, L. J. Gallagher, Charles R. Hagwood, R. N. Kacker
• 1998

Software testing is hard, expensive, and uncertain. Many protocols have been suggested, especially in the area of conformance veri cation. In order to compare the e cacy of these protocols, we have… (More)

A fast algorithm for elastic shape distances between closed planar curves
