A Possible Neural Mechanism for Computing Shape From Shading
Article PDF (1.13 MB)
Abstract

A simple neural mechanism that recovers surface shape from image shading is derived from a simplified model of the physics of image formation. The mechanism's performance is surprisingly good even when applied to complex natural images, and is even able to extract significant shape information from some line drawings.
