The University of Bath released an iris dataset back in 2005
http://www.bath.ac.uk/news/archive/2005/11/15/iris151105.html
which has been widely used to evaluate the iris recognition algorithms performance since then.
It is considered now one of the classic iris recognition datasets.
I contacted the University in order to obtain the dataset from them, but the academic who worked on the iris dataset has long since left Bath and it is no longer available from the University.
Is there a way to get this dataset in order to run performance tests of the iris recognition algorithm and compare it to different iris recognition algorithm implementations?
