Characteristic and Necessary Minutiae in Fingerprints
Fingerprints feature a ridge pattern with moderately varying ridge frequency (RF), following an orientation field (OF), which usually features some singularities.
Methodology
DOTmark - A Benchmark for Discrete Optimal Transport
The Wasserstein metric or earth mover's distance (EMD) is a useful tool in statistics, machine learning and computer science with many applications to biological or medical imaging, among others.
The Shortlist Method for Fast Computation of the Earth Mover's Distance and Finding Optimal Solutions to Transportation Problems
Our starting point is the well-known revised simplex algorithm, which iteratively improves a feasible solution to optimality.
