Computer Learns to Recognize Rough Sketches
A new algorithm developed at Brown University and the Technical University of Berlin is the first computer application designed for â€œsemantic understandingâ€ of abstract drawings, and the research team says it could improve search applications and sketch-based interfaces. Someday, building on this research and other line-drawing computer recognition, you might be able to finger-draw something on your iPhone and turn up a real answer.
The program can identify simple abstract sketches 56% of the time, compared to humansâ€™ 73% average. Even those sorely lacking in verisimilitude can be detected, which is the key breakthrough here. Computers can already recognize accurate sketches, like a police sketch of a suspect compared to photos of a face, for example. But for the type of abstract sketches we all grow up with, itâ€™s a different challenge.
