Someone can help to visualize or plot the morphological structuring element, created by function 'strel' for only 'disk' structuring, in Matlab? Thanks.
Yes, it's a big strange, but I assume that for efficiency reasons,
strel returns a special type that's a structuring element type.
You have to use the getnhood function as in this link, something like this:
se3 = strel('disk',15);
nhood = getnhood(se3);
imagesc(nhood); axis xy; colormap('gray');
