Abstract:
Visual search is the task of finding a target in an image
against a background of distractors. Unique features of targets
enable them to pop out against the background. It is known that the
ease of target detection can change when the roles of figure and
ground are switched. The mechanisms underlying pop out and
asymmetry in visual search have been elusive. This paper shows that
a model of segmentation in V1 based on intracortical interactions
can explain many of the qualitative aspects of visual
search.
