I suggest using a template based matching. Use a training set of fingerprints, make them all normalized in oriƫntation and then try to create an 'average' fingerprint. Use that template to match in all possible orientations (unless you know the orientation) the template with the input image and see where the highest responses result! That will probably be your finger print!
