Question

I have a function which calculates image texture (using 2D convolution via NLFILTER):

y=imagetexture(image,winsize)

In my matlab workspace I have 3 variables; the red green and blue bands of an image (r,g,b).
How can I repeatedly run this function on each band (r,g,b) for various window sizes?
e.g. 3×3,5×5,7×7 etc.

Thanks

If your red, green and blue image bands were stored in variables r, g, and b, would this do what you need?

winsizes = [3, 5, 7];

for i = 1:numel(winsizes)
    yr{i} = imagetexture(r, winsizes(i));
    yg{i} = imagetexture(g, winsizes(i));
    yb{i} = imagetexture(b, winsizes(i));
end
