Could be anything. stdfilt() is a commonly used texture detection function. You might also use SURF, Hu's moments, Hausdorf distance, CBIR methods, or any number of other things.

Usually people show us an image when they ask for image processing advice.

MATLAB: I have 2 contours on the same plot and I want to differentiate them with colours so I can see the difference.

I = imread('rice.png');
figure,subplot(121),
imcontour(I);ax = gca;
colormap(ax,'cool')
subplot(122);
imcontour(I);ax = gca;
colormap(ax,'hot')

EDIT:

Change LineColor

I = imread('rice.png');
figure,
imcontour(I,'LineColor','r')
hold on
I = imread('cameraman.tif');
imcontour(I)

MATLAB: Undefined function or method of type char

Is this the entire code? If so, then one problem is that when you get to this line:

r = c(:,:,1);

you have not yet defined the variable c, so MATLAB can't make the assignment.
