Question Iris Recognition: Iris segmentation
Who can tell me about how to apply the Derivative filters
and Smoothing filters in Daugman's Integro-Differential
operator?.

I'm programming it on C++ for my thesis project. I have
applied Integro-Differential operator already but it just
looks like trying to find both pupil and limbus edges. It marks
concentric circles far from these components and sometimes,
it marks whatever as an edge. I'm specifing a radius range
to look for both circles but I think I'm not applying the
filters correctly. It's also slow.

Has anyone worked on Iris segmentation yet?.
Which method have you applied to find both pupil and
limbus edges?. It would be better for me if you have applied
some approach to find eyelids and set noise masks
due to eyelashes. It's supposed to be considered in
Hamming Distance when doing matching step.

Anyone who had worked on one or more of the above
detailed topics, please contact me to:

* memcpy_0xffcd@hotmail.com
* masm32_0f538h@hotmail.com
* ocnwtnsys32@yahoo.com

I hope someone can help me with what I'm trying to do.

Dear ...

In my final year project ... i implement the follwing algorithms :

1- Canny edge detection : it is the best algorithm for edge detection.
2- Apply circular Hough transform to localized the pupil and the iris circle.
3- To remove eyelids, i implemented my own method using linear Hough transform to detect the lower and the upper peaks of the eylids, but you can use parabolic Hough transfom.

See http://www.samer2.8m.com ...

Godd luck ...

Talking
I feel so happy you have answered me, Image processor.
Gee, I have to make a web page like yours when I have
my project ready. It will be very helpful for people are
also working on Iris Recognition.

I'm still working on the segmentation step and I'm looking for
information about Iris Segmentation. I found a C++ code
that performs Canny Edge Detection, but it doesn't seem to
work very well.

Could you please show me your algorithms? (I'm not
asking you to give your source code to me). I'll be very
thankful then.

You can write to one of my e-mail addresses:

* memcpy_0xffcd@hotmail.com
* masm32_0f538h@hotmail.com
* ocnwtnsys32@yahoo.com

I can also send my whole iris recognition source code to you.
Thank you anyway, friend.

Bye

Smile Iris and Fingerprint Recognition in Matlab
Hi all,
Me and my sister are students of The University of Queensland as computer engineer,and we have to prepare a project about fingerprint and iris recognition in matlab to pass the lesson called image processing. Actually, we have to study about our senior project, so we don't know matlab yet. If you send me your code and tell how we run this code, we will be very pleased. If you think this is not reasonable to give us your code, we can share our codes about something else that you can use. I am waiting your answers as soon as possible. you can contact me from my mail. Thank you all.

Hi ,
i m also working on iris recognition project and i m trying to implement the daughman method for this but for locating the iris he is using polar cordinats for that and contour integral and a gussuian function but i have a great confusion that how we will decide the center and redius . can anybody help me for this part ????

Post Iris Recognition Software And Dll
I have been receiving too many requests for my iris
recognition project by e-Mail. Thus, I have just
created a web site for those who are interested in
it (and in more information as well) so that they can download
the iris recognition dll and the executable program from there.

As I told you before, my system has been developed
with Visual C++ 6.0, and my dlls can be useful for
several of your projects and research on the area
of iris recognition.

My web site is http://xpertsolutions.fortunecity.es

You should click on "Services" in order to download
the iris recognition dll and the executable program.
Source code -or an improved version of the program-
will be provided to you only when you submit the application
form filled out properly. If possible, send scanned personal
documents for verification. I need to be sure what you really
need the source code for. In many cases, the people
who required my source code didn't write me anymore,
so I couldn't determine what they did with it eventually.

You can also apply for more improvements to be made
over my system and dlls if you are interested in providing
some help.

Documentation of all the functions in the iris recognition
library has been incorporated, as well as the application
form for those who want to help me make some
improvements in my software.

Thank you for your interest.
All yours:
