Never heard of it. Why don't you want to use the skeletonization capability built into bwmorph()?

Azriel Rosenfeld published a number of image thinning algorithms. You need to be more specific. See for example here

在 MATLAB Online 中打开

doc imfilter

or if you're like me and don't like imfilter because it's evil

doc conv2

will take care of that algorithm pretty painlessly for you.

Cool. Now we have two dogs in your logo. What are their names?

I don't see how a convolution or imfilter can do a non-linear operation like skeletonizing, rank filters, or other morphology where you preferentially assign values. For example, an erosion is a local min - how do you do that with convolution?
