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 VMG mendozag@ecn.purdue.edu ------------------------------ Date: Fri, 20 Oct 89 01:03:47 EDT From: harnad@clarity.Princeton.EDU (Stevan Harnad) 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.

Previc Crew Technology Division USAF School of Aerospace Medicine 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. ------------------------------ End of VISION-LIST ********************
