PhotoSketch: Internet Image Montage from tao chen on Vimeo.
Designed by a team at the National University of Singapore, PhotoSketch is the latest and greatest in image creation systems. The full description of how it works can be found here, but the basic process is this:
Draw a basic object, name it and repeat this for any other objects you want in your picture, then name the background. PhotoSketch then searches the Internet for images that match the descriptions given, and after a bit of sorting out, you have all the elements necessary for seamless stitching. The possibilities seem endless. Check out the video!
