image processing question

Why isn't there a way to search for images by drawing a rough outline of a part of the image and returning all images that roughly match that outline?

I know edge detection algorithms aren't perfect but surely someone has thought of this - so why hasn't Google made this already?

By the way, has anyone figured out what made kikes so ugly in the first place? It's like someone picked all the worst features a humanoid could have and slapped them all together to form the first jew.
