I found this pretty good list of Iris Recognition open-source codes. I am really appreciate work of the first author, thanhkien84. I asked myself, how to improve it? I have decided to add my value.
I have checked all links and found replacements for stale links to projects OSIRIS, UND.
In the year 2003 there was only one iris recognition open source code from Libor Masek. His source code, written in Matlab, has been the baseline for generations of iris recognition coders. Recently there are a number of new open source codes come up. They are more mature and meet state-of-the-art accuracy. I summarise them in a list here for your reference.
