How do I find Waldo with Mathematica?
... many images of Waldo - all variations of him sitting, standing, occluded, etc.; shirt, hat, camera, and all the works. You don't need a large corpus of Waldos (maybe 3-5 will be enough), but the more the better.

Finally, trees can also carry weight information in the nodes, permitting wei...
