Rumor has it that the Renaissance painter Raphael used to impress the nobles of this era with his ability to render seemingly perfect circles; having, undoubtibly, tried this yourself you know how difficult that can be. I have even had competitions with people to see who could draw the most round circle; but usually, those competitions ended in conclusionless because there was no real way to judge whose circle was best… especially if they were close. But now, as I did last week with the “Gradient Helper,” I have invited our friend the computer to come help us judge our circles.By modifying and expanding the Blob Detection library in Processing, I was able to create a program that takes an image, looks for enclosed shapes (circles), finds the average radius of those shapes, and then computes the average radial deviation of the vertexes of the shape. Yay. This was hard though… and its not as tight as it should be… but it is a good first step.
