  • Perceptual closure is one of the principles by which the visual system groups disjointed contour segments belonging to a single object. Recently it has been reported that grouping based on perceptual closure operates only upon contour elements of a consistent contrast sign and is eliminated when closed contours contain contrast reversing segments [Elder, J. & Zucker, S. (1994) A measure of closure. Vision Research, 22, 3361-3369]. The present study re-examines the effect of contrast polarity… CONTINUE READING
