The important role of contours in visual perception has been recognized
for many years (e.g., Wertheimer 1923/1938). While early Gestalt
insights derive from observation of highly idealized images, decades of
computer vision research have demonstrated the computational complexity
of inferring and exploiting contours in natural images. Physiological
data, while generating some intriguing clues, are often too local
(single unit recording) or too global (imaging) to provide the data
