hello, i m doing project on eye blink and face turn detection using matlab. i have completed the face turn detection, but i m struck with eye blink detection. i m monitoring the right eye i m able detect the eye in real time using continuous snaps through webcam, but not able to detect the blink ..i have ploted eye ,graph & face in a figure.with what value should i compare the detected eye image to find weather eye is open or close???? i m uploading my code, please help me in finding the blink detection.
clc;
close all;
clear all;
cam=webcam; c1=0;
EyeDetect = vision.CascadeObjectDetector('EyePairBig');
for co=0:650
I=snapshot(cam);
BB1=step(EyeDetect,I);
ay=sum(BB1(:));
if(ay==0)
c1=c1+1;
if(c1==100)
disp('turn the face');
end
else
Eyes=imcrop(I,BB1);
k=size(Eyes);
l2=k(2)/3;
w=round(l2);
ey=imcrop(Eyes,[0 0 l2 k(1)]);
figure (1),
subplot(3,1,1)
imshow(ey);
k2=size(ey);
a=rgb2gray(ey);
sa=sum(a(:));
subplot(3,1,2)
plot(1:size(a,1),mean(a,2));
c1=0;
subplot(3,1,3)
imshow(I);
clc;
end
end

Hi, I imagine that after so much time you managed to solve your problems with this algorithm for eye blink detection. If you did, is there any code you can share with me? I am beginning to work on an application requiring bliking detection, so it would be great to have some working code to play with. In the opposite case, if you are still working on the problem, I would be glad to contribute. Best regards Giorgio
