Matlab code for some of my research and some general
image processing functions are available (soon).

Singular Points Detector for Fingerprint Images
An
efficient algorithm for core and delta detection in fingerprint images
using signum change curves in the directional images. The algorithm is
further optimized to achieve faster computational speed. Related papers:

High-Resolution Segmentation for Fingerprint Images
An
pixel-wise algorithm for segmentation of fingerprint images. The method
uses three pixel features,
being the coherence, the mean and the variance. An optimal linear
classifier is trained for the classification per pixel, while
morphology is applied as postprocessing to obtain compact clusters and
to reduce the number of classification errors. Related papers:
