PhotoSketch, a new image manipulation program that combines stick-figure sketches, internet image search and pattern matching, seems to be spreading like wildfire. Created by five Chinese students at Tsinghua University and the National University of Singapore, the tool takes a basic sketch and simple labels and turns it into a polished image. "Although online image search generates many inappropriate results, our system is able to automatically select suitable photographs to generate a high quality composition, using a filtering scheme to exclude undesirable images," say the PhotoSketch team in an abstract outlining the tool. "We also provide a novel image blending algorithm to allow seamless image composition. Each blending result is given a numeric score, allowing us to find an optimal combination of discovered images. Experimental results show the method is very successful."
