PhotoSketch is an Internet Image Montage project from five Chinese Computer Science and Technology students at Tsinghua University and the National University of Singapore. The basic premise, which they present in the form of a research paper [pdf], works like this:
Step 1. Draw the outlines of the figures you want in your picture anything from seagulls to a Mercedes, whatever tickles your fancy,
Step 2. Add labels for each of the items, as well as for the background.
Step 3. PhotoSketch will then find real-life images to match your doodles and put them together in a Photoshopped image that will make your jaw drop.
