| summary | When you look AT a picture you see a planar object covered with pigments in a certain simultaneous order; when you look INTO a picture you experience "pictorial space". Pictorial space is filled with "pictorial objects" that appear to have positions, spatial attitudes, shapes and material properties. "Pictorial shape" is a geometrical property that is a purely mental entity based on "pictorial cues" but contains a significant "beholder's share". In many cases human observers exploit the cue structure completely, then the beholder's share coincides with the ambiguity left by the cues. The beholder's share may be identified with the group of proper movements or congruences of pictorial space, thus defining its (non-Euclidian) structure. "Pictorial shapes" are invariants under these congruences.
Jan Koenderink graduated in Physics and Mathematics in 1967 at Utrecht University. He was associate professor in Experimental Psychology at the Universiteit Groningen, then in 1974 returned to the Universiteit Utrecht where he presently holds a chair in the Department of Physics and Astronomy. He founded the Helmholtz Instituut in which multidisciplinary work in biology, medicine, physics and computer science is coordinated.He has received an honorary degree (D.Sc.) in Medicine from the University of Leuven and is a member of the Royal Netherlands Academy of Arts and Sciences. His current interests include the mathematics and psychophysics of space and form in vision and active touch, the structure of perceptual spaces, and ecological physics, including applications in art and design. |
