Subject: Reference wanted
I am looking for the exact reference to the following paper:
``Parallel Processing of a Knowledge-Based Vision System,''
by D. I. Moldovan and C. I. Wu.
It might have appeared as a conference paper around 1986 or 1987.
I'd appreciate any pointers. Thanks in advance

Subject: Facial Features: Computer Analysis
I would like information about software and hardware for representing
and analyzing faces and facial features. Ideally, I would like
something that, like Susan Brennan's program for generating
caricatures, has been standardized across large samples of faces and is
able to pull out the facial parameters that carry the kind of
information we pick up when we look at faces.
The purpose of the project is to find detectable, quantifiable features
that will predict the degree of genetic relatedness between two people
from images of their faces.
Please send the replies to me, not the net. If anyone wants me to share
the responses with them, send me an email request.

Functional Specialization in the Lower and Upper Visual Fields in Man:
Its Ecological Origins and Neurophysiological Implications
by Fred H. Previc

Brooks AFB, TX 78235-5301
Abstract: Functional specialization in the lower and upper visual
fields in man is reviewed and interpreted with respect to the origins
of the primate visual system. Many of the processing differences
between the vertical hemifields are related to the distinction between
near (personal) and far (extrapersonal) space, which are biased towards
the lower and upper visual fields respectively. It is hypothesized that
a significant enhancement of these functional specializations occurred
in conjunction with the emergence of forelimb manipulative skills and
fruit-eating, in which the fruit or distal object is searched and
attended to in central vision while the reaching motion of the hand and
other related manipulations are monitored in the proximal lower visual
field. Objects in far vision are searched and recognized primarily
using linear/local perceptual mechanisms, whereas nonlinear/global
processing is required in the lower visual field in order to perceive
the optically degraded and diplopic images contained in near vision.
The functional differences between the lower and upper visual fields
are correlated with their disproportionate representations in the
dorsal vs. ventral divisions of visual association cortex,
respectively, and in the magnocellular and parvocellular pathways that
project to them. The division between near and far visual functions may
also have contributed to the transformations of the lateral geniculate
nucleus, superior colliculus, and frontal visual areas which occurred
during the evolution of primate vision.
