CSPN is a minutiae-based fingerprint verification algorithm that extracts minutiae by adaptive tracing the gray level ridges and matches minutia sets based on the minutia local and global structures. In addition, CSPN employs some unique techniques such as image segmentation adaptive to the image contrast and area, selective image processing, higher order statistics and ridge associated post-processing. More detailed information can be found in the following publications:
 X. Jiang et al., "Minutiae Extraction by Adaptive Tracing the Gray Level Ridge of the Fingerprint Image", IEEE ICIP'99, Japan, 1999.
CSPN was developed mainly for portable stand-alone system where the algorithm speed and capability of recognizing partial fingerprints are emphasized for low cost processors and small fingerprint sensors. In addition, the algorithm is rotation and translation invariant. For more information please contact Dr. Xudong Jiang, email: firstname.lastname@example.org.Detailed results on DB1
