They use different algorithm so of course they're not going to agree on every single pixel. You can look up the precise algorithms online if you want - no sense in me explaining them, or copying and pasting the descriptions here, when you can just look them up.

If you like the edges that your algorithm gives you, then you can count them with bwlabel():
[~, numEdges] = bwlabel(binaryImage);
