Fingerprint recognition using python
3.0
#A year of active development of fingerprint identification algorithm: 2012? Summarize the implementation of biological method course of fingerprint identification algorithm development in University of Wroclaw, Poland. #How to use it is just to do python filename.py ——Help how to execute file algorithm algorithm Poincar é index to find the fingerprint of singularity. How it works (more detailed description [here]（ http://books.google.pl/books ？ Id = 1wpx25d8qowc and LPG = pa120 and OTS = 9wry0rosb7 and DQ =%% Poincare & amp; HL = 20index 20fingerprint PL & amp; PG = pa120 # v = onepage & amp; q = Poincare%% & amp; F = false 20index 20fingerprint)): * divide the image into blocks_ size ` ` `*Each block: * calculate the direction of the fingerprint ridge line of the block (i.e. what is the ridge slope angle between the ridge and the horizon) * sum up the angle difference (direction) of the surrounding blocks * there are 4 cases: * the sum is 180 (+ NAI) ring found * the sum is 180 (+ NAI) Delta found * the sum is 360 (+ NAI) - thread found Python script will mark the singularity boundary: * Red Ring * GREEN delta * Blue thread, for example: ` ` ` Python poincare.py Image / 16 1 - smooth PPF1.
