Spatial configurations for visual hyperacuity
Spatial configurations for visual hyperacuity is a scholarly work, published in 1977 in ''Vision Research''. The main subjects of the publication include Hyperacuity, optics, computer science, color constancy, artificial intelligence, Vernier acuity, physics, curve, psychophysics, ophthalmology, displacement, Vernier scale, absolute threshold, sensory threshold, visual perception, orientation (vector space), and color psychology. Two widely-held concepts are thus found to lack validity: that averaging of local signs along lines or contours is a prerequisite to hyperacuity and that the detection is necessarily performed according to the criterion of explicit or implicit orientation.
