I have paths in SVG file with d attributes with values like

I want to classify this path into geometric shapes like circle, rectangle, ellipse etc programmatically. When I say programmatically I mean no image processing techniques should be involved i.e. strict requirement.
Is there any way to do this. Please guide me.

  • $\begingroup$ This is in fact a bit error prone. I do some amount of cnc work and due to the controller of some machines it would be great to identify circles and circle segments. But the thing is to identify circles well the software needs to be quite agressive at detecting them. Which is bad because it kills the carefully constructed C2 continious fillets of some users. The problem being that a bezier is never a circle so there is allways some guesswork involved especially since there are many ways to approximate a circle. $\endgroup$
