Singular Points Analysis in Fingerprints Based on Topological Structure and Orientation Field
Abstract. As an important feature of fingerprints, singular points (includingcores and deltas) not only represent the local ridge pattern characteristics, but also determine the to...

Robust and Efficient Skeletal Graphs
There has recently been significant interest in using repions based on abstractions of Blum's skeleton into a graph, for qualitative shape matching. The application of these ...
