enhancement algorithm is a useful step to employ prior to minutiae extraction. The Crossing Number method was then implemented to perform extraction of minutiae. Experiments conducted have shown that this method is able to accurately detect all valid regions, and will disregard an image if it is severely corrupted. However, there are cases where the extracted minutiae do not correspond to true minutiae. Hence, an image post processing stage is implemented to validate the minutiae.
