Query: Geometric Fingerprint Recognition via Oriented Point-Set Pattern
  Matching   Motivated by the problem of fingerprint matching, we present geometric
approximation algorithms for matching a pattern point set against a background
point set, where the points have angular orientations in addition to their
positions.
