ptresset writes with a snippet from Wired: "Pop along to the Tenderpixel art space in Soho this month, and you could grab a drawing of your mug, sketched by one of Patrick Tresset's robotic arms. The sketching bot is called Paul. It starts off the exhibition by scanning the room and looking for people with its motorised eye. When it spots a human face, it uses an edge detection technique called Gabor filter (which is modeled after cells in a human's visual cortex) to pick out the salient lines."
