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.
