Find the People: Lisp Programming Contest sponsored by TC Lispers July 31st, 2010
Patrick Stein

Your Lisp program will be given two input images from the same web cam. The first image will contain zero people, the second image will contain at least one person.

Your program’s goal is to find the people. You will get points for emitting the pixel coordinates of a pixel inside a person. You’ll get bonus points if it’s a head pixel. Be careful, though. You’ll lose points for emitting more than one pixel per person.
