Hello
I am working on some code to segment my iris and my pupil, I want to be able to have a crosshair or circle that can identify my pupil and also another circle that can detect my iris. I have brown eyes so it is a little difficult to do this however this is what I have so far maybe someone could help me? If anyone knows how to segment brown and black colors?
Eye=imread("niceeye.jpg");
eyegray=rgb2gray(Eye);
bweye=imbinarize(eyegray)
edge=edge(bweye,"canny")
imshow(edge)
