Math Monday: Candy Images

by George Hart



Tim Chartier at Davidson College has discovered that if you make things out of candy there’s no lack of volunteers to help you clean up. He takes images and transforms them mathematically into arrays of candy pieces. Here you can see President Obama, as rounded to the set of m&m color values. Mathematically, the algorithm picks the available color which is closest in red-green-blue-space to the average of the pixels it replaces.
Tim’s program has controls that allow the user to change the image, the candy, and the resolution.  Since Easter is coming up, you may find a use for this recipe to make another U.S. president, this time from 400 peeps:
As Tim notes on his blog, “The best part is taking it apart!”
