Please help me to make segmentation for eye's image, i want to segment the sclera (Whites of the eyes)of eye.

Please help me to make segmentation for eye's image, i want to segment the sclera (Whites of the eyes)of eye.

Please post a sample image.

i don't know how to write the code to segmented it, i want to segment many images like that, not just one image .

[Abdul Rehman]

I=imread('K.jpg');
L=rgb2gray(I);
BW1 = edge(L,'Canny');
imshow(BW1);
radii = 78:1:92;
h = circle_hough(BW1, radii, 'same', 'normalise');
peaks = circle_houghpeaks(h, radii, 'nhoodxy', 15, 'nhoodr', 21, 'npeaks', 1);
imshow(I);
hold on;
for peak = peaks
    [x, y] = circlepoints(peak(3));
    plot(x+peak(1), y+peak(2), 'g-');
end
hold off
figure;
imshow(I);
a=peak(1);
b=peak(2);
c=peak(3);
% Customerlized Mask
m = zeros(size(I,1),size(I,2));
m(20:120,20:120) = 1;
% Built-in Mask
seg = chenvese(I,'small',1000,0.02,'chan'); % ability on gray image
%-- End 
imshow(seg);

Go here for robust algorithms: http://iris.usc.edu/Vision-Notes/bibliography/people898.html#Finding%20Facial%20Features,%20Eye%20Detection

[Malak s]

thank you , but i need the code of it

[Image Analyst]

But you've bought MATLAB, haven't you? I assume with the intent of writing code. So pick a paper and start writing. Or else ask the authors if they can give you the code, though it may come at a price if you ask them for consulting services.

[Malak s]

can you give me the name of some authors that you know please?

[Image Analyst]

I don't personally know any of the authors on that list of eye detection papers.

[Ahmad Almazloum]

Have got the code of the sclera detection (the white area)? Please if any body have the algorithm ou matlab code, please send it to me (my email; [e-mail])...thanks in advance.

[Image Analyst]

The algorithms are listed in the link I gave. Did you look at it? I don't have any of their code, but perhaps if you ask the authors they might be able to offer something.
