Psychophysical evidence for global feature processing in visual texture discrimination

Not Accessible

Your library or personal account may give you access

Abstract

By defining texture as a global feature attained by integration over the image domain, we show that texture discrimination can be predicted for a special class of visual textures (composed of paired dots) as a function of such global features. We derive a psychophysical law based on these global features and show that differences in the variance of orientation, but not of dipole length, result in texture discrimination.
