multiple registrations [242], algorithms that estimate the mean distortion present
in the considered data [243], and techniques for estimating the distortion models
obtained by different finger placements on the sensor [244].
4.5.4.3 Other Feature-Based Methods
Other fingerprint matching methods use features extracted at different levels as sup-
port information for processing a matching score based on the minutiae sets, or
directly process features extracted at Level 1 or at Level 3.
Most of these matching methods are based on texture analysis performed at
Level 1. One of the most commonly used techniques in the literature is ...
