Nervous systems have evolved impressive abilities to extract useful information about the environment from images. Jumping spiders use their eight-eyed visual systems to detect prey, discriminate objects, and navigate;most mammals can readily segment moving objects in a scene and estimate velocities to mediate complex visuo-motor tasks; and primates can readily infer the 3D surface structure of their world from two dimensional images. How are these tasks - all of which lie beyond the current abilities of modern machine vision systems - accomplished by neural circuits in the brain? This week will bring together a combination of experimentalists and theorists who are attempting to understand the neural mechanisms of visual perception. This workshop is jointly sponsored by MSRI and the Redwood Neuroscience Institute. The Tuesday, February 8, 2005 session will be held at RNI. Because space at RNI is limited, attendees should apply in advance for Tuesday's session only by sending an email to Teri Fry tfry@rni.org . There will be a reception after the session at RNI, Tuesday, Feb. 8 at the Computer History Museum in Mountain View.
