Page 3 - are there any one who works on iris recognition project?

hi there

I just started with an iris recognition project. I downloaded the code from URL and tested it with the images from the chinese iris database. Looks pretty nice for the first results.
Now I'd like to grab images from the panasonic authenticam. Is there a possibility to do so.
I read something about an SDK but I didn't find the information where to get it.

(besides, I installed the cam and it is working correctly on my System)

thanks, mathu

hello,gs30,i download the source code from the site.but now i have one error in running the source code.
% ??? Error using ==> conv2
HCOL, HROW, and A must be full double.

Error in ==> C:\MATLAB6p5\toolbox\matlab\datafun\filter2.m
On line 72 ==> y = conv2(hcol, hrow, x, shape);
%
i just want to know where used the function 'conv2'.and where is the error?
Thank you!
Welcome everyone to answer me!

hi i'm creation. i'm trying to implement iris recognition for my final sem project. could u help me?
i don't know much about it. could u plz suggest me some site where i can get easy going information.
thanx

When i run it,it shows error in canny function!the func filter2 is used wrongly!!!!And i corrected it,when go down,the func houghcircle is a dead-recycle!!!!!!why????who can tell me????

u must use the image from the iris database

yes ,good news,it works!but somebody can tell me how many bytes u got from the source code.i got 20*480 bytes.it is too big.it may be 512 bytes!!!why?

Thankx!!!

Hello friends
i am a new user to this forum.
I downloaded a matlab code for iris Recognition from
URL
but I have no idea of how to run it, can someone let me know how to start with the code.

Thanks

You must use "GRAY" scale image rather RGB image.
I guess then it would work perfectly.

Referring to gs300, there are 5 main steps in iris recognition
1- image acquisition .
2- image preprocessing .
3- iris localizing .
4- building template .
5- iris matching .


The step that I don’t understand is no. 4,
If I’m not mistake, there’re steps called feature extraction and feature encoding before an iris template can be made (Thx to AnasMe). I still don’t understand how to extract a feature from an iris image. Can anyone help me please????

Hello,

I am considering to implement daugmen's segmentation method. Anyone can tell me how can I start? I read through his PAMI paper, but no deatils about the programming details.

thanks!!

Neat

i m working on iris detection i ve downloaded ths code but is having a problem in executing it wid the iris database there is a hang up

i m having problem in th hough circle function plz someone help i m having my presentation after two days

The feature Extraction step is the same as creating the iris code. the code is the features of the iris. You may read a paper to see how to use wavelet in feature extranction..

Thanks Everybody for being interesting in Iris recognition.

There are many enhancement to the the hough circle detection. you may try to update it. a simple update is to follow this:

in the hough circle code, it draw a circle of each radius for each edge point.
you may draw circles for each edge point by each radius.
(i.e. compute the circle points for each radius. then draw the circle for each edge points using this precalclated points) this will reduce the time of computation. instead computing the circle points N*rd times, it will only be computes rd times.
where rd is the number of radii and N is the number of edge points.

there are some other enhancements, you may try to understand the code and enhance it or even replace a pice of code that can be implemented in a faster way.

I wrote a code depending on Libor code, but with faster computation to about 1/8 of the time.
thanks to all,
