A New Fast Automatic Technique for Fingerprints Recognition and Identification

Because automatic image analysis depends greatly on image segmentation, a new fast edge algorithm is proposed to trace ridge lines of the fingerprint images. Edge line skeleton method, based on edge point categorization, is also introduced. Fingerprint image core point is detected by an adaptive technique suggested in this work. The core is based on slicing the edge lines into four groups representing the four possible directions (i.e. vertical, horizontal and two diagonals). A set of 34-measure features are proposed for recognizing and identifying fingerprint images.
