Where's Waldo is a searching game where you are presented an image of some scene, and your goal is to find a man named Waldo in the picture.
Here are a couple pictures showing what Waldo looks like. He always wears a red and white striped sweater and hat, blue pants, brown shoes and hair. He can be with or without accessories such as a camera, glasses, or a cane.
And here are some of the scenes where Waldo is hidden. (You can right click the images and go to the image source for higher resolution.)
Write a program that processes the images (provided as input however you like) and finds Waldo in as many of the above five images as possible. Your program is scored using the following formula
codeLength / numberOfPicturesInWhichWaldoIsFound
and, of course, the lower the score, the better.
