it works great !! for those who uses CAsia interval or CASIA Iris-V3 you must to fix the min and the max Radius [95 150] respectively, and to apply the Enhace histog Equalization "histeq.m"
but if you use the Casia1 it works by fixing on [95 105] without histeq.
I've some prblm with the Classification step if someone could help I'll apreciate (wich method or Algorithm i should use to extract the features ..!!).
