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

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.
