Maximum curvature:
This method will try to extract the centre lines of the veins. This is done by calculating local maximum curvatures in cross-sectional profiles of a vein image. The method is supposed to be robust against varying vein widths and non-uniform brightness.
Repeated line tracking:
This algorithm will start at several random points and will try to track a line. If a pixel has been visited by the line tracking algorithm multiple times it is likely to be a vein. A movie showing the algorithm in action can be found here:

The file "miura_usage.m" gives an impression of how to use the feature extraction methods. Finger region localisation can be found here:

The Biometrics Security and Privacy Group at Idiap, in Switzerland have created a Python implementation of the Miura repeated line tracker and other vein biometric algorithms. See https://www.idiap.ch/software/bob/docs/bob/bob.bio.vein/stable/index.html# for details.

Please leave a comment, if you like it, find a bug, or know (made) good improvements to the code.
