I am able to find pupil circle but not able to find iris circle from these images. I'm using Iris Recognition Libor Masek code for segmentation. http://www.csse.uwa.edu.au/~pk/studentprojects/libor/sourcecode.html Can anyone tell me if it is possible to segment iris from these images

No, this eye pretty much has no iris. Best you can do is to find the center of the pupil and go out a predetermined radius from the center, assuming this iris will be the average diameter iris.

Thanks for the reference. I was able to segment the 1st eye.
and this is normalised and polar form image
Will this be useful for Iris recognition? I mean the information will be enough for performing matching?

I would guess not. You have clutter from the upper eyelashes, a line from the lower lid, and no structure in the iris. But I'm not an expert in iris recognition. I expect you'll learn a lot more from those papers I referred you to than from me, once you get around to looking at them, which I hope you will do.
