What does "Apply the local max" to it mean? Do you mean imdilate(), which does the local max in a sliding/local window?
edtImage = bwdist(binaryImage); % Calc Euclidean Distance Transform.
% Now get the local max in a 5x5 window everywhere.
localMaxImage = imdilate(edtImage, true(5)); % Whatever window size you want.
Let me know if you want the local max only if it's at the center of the window, like if you want to find ridgelines or something.

That's a separate question. What about this question about distance transform followed by local max? Didn't I answer that?

You did it in your other post. Can't you just click on the green image with the brown frame and upload one from your hard drive? Or type alt-printscreen and go to http://snag.gy and paste it in and then paste the URL it gives you into the "Web" field when you click the image icon.

Still didn't work. All I see is a missing image symbol.
