Post Program learns to recognize rough sketches of objects

Researchers at Brown and the Technical University of Berlin have produced a program thatcan identify simple sketchesof objects almost as well as humans. The computer application enables "semantic understanding" of abstract sketches as they are being drawn in real time. The research was presented at computer graphics conference SIGGRAPH and thepaper is now available online.

Computers can already match sketches to objects provided they are accurate representations'e.g., matching police sketches to actual faces in mug shots. However, more abstract sketches'the more cartoonish drawings that most people can easily produce'present a different challenge.

For example, in order to draw a rabbit, a person might draw a cartoonish creature with big ears, buckteeth and a fluffy cotton tail that another person would recognise despite the fact that it bears little resemblance to an actual rabbit.
