Huh, im too tired now writing so many post and boring you, so here i decide to post about one of my paper biometric recognition. I just think this post will be useful for you all to know about biometric iris recognition. Biometrics is the development of statistical and mathematical methods applicable to data analysis problems in the biological sciences. A biometric system provides automatic recognition of an individual based on some sort of unique feature or characteristic possessed by the individual. Biometric systems have been developed based on fingerprints, facial features, voice, hand geometry, handwriting, the retina, and the one presented in this thesis, the iris.
