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.

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