Why have you changed the question?

Thought it was a double post.

What do you mean? Are you dealing with a gray scale image or a 3D true color RGB image? Like each color plane of an RGB image is a layer? Or do you mean that you want to split the image up vertically or horizontally into the top third, middle third, or bottom third (like Azzi did for a gray scale image), or left third, middle third, and right third? Please clarify.

Then they are not "layered" they are stacked. Have you tried imcrop()?

[n,m]=size(im)   % im is your image
id=fix(n/3)
im1=im(1:id,:);
im2=im(id+1:2*id,:);
im3=im(2*id+1:n,:);

Like he said, im is your image variable. In your code you might have read in an image with imread like this

im = imread(fullFileName);

What variable name are you using instead of im in your code?
