Current Research: John M. Foley
(pattern vision; visual space perception, visual-motor control, image quality) Dr. Foley works on the experimental and theoretical analysis of visual perception,
information processing, and visual-motor control. He has an applied research
interest in improving the quality of video imagery. He has pursued a variety
of research problems ranging from the detection of visual patterns to the geometry
of visual space. In pattern vision, he is working on pattern detection, masking
of one pattern by another, pattern adaptation, and spatial context effects
on pattern detection and appearance, and attentional effects. These studies
are designed to test and further develop a computational model of human pattern
vision that he has proposed. In space perception, his interests include stereopsis,
integration of distance information, size perception, and geometrical theories
of space perception. Humans often make systematic errors in indicating the
positions of objects in space and the sizes of objects and extents between
them. Nevertheless, they are able to perform accurately in spatial tasks. Studies
of visual-motor coordination focus on these errors and how they are corrected
by learning with error feedback. The image quality studies are concerned with
defects that are introduced into video images when they are compressed and
how the impact of these defects on perceived image quality can be minimized. Faculty Home | Current Research | Selected Publications
