There is both physiological and psychophysical evidence that the first stages of
visual processing analyze the retinal image into a patchwork of localized
one-dimensional components, which may variously be conceived as representing
bars, edges, local Fourier components, Gabor functions, or what have you. In any
event, such an analysis brings the aperture problem in with it from the very
start. The visual system must go from the local motion of one-dimensional
components to the percept of a single coherently moving pattern.
