A comparison of Fourier analysis and feature analysis in pattern-specific color aftereffects.
Subjects were adapted to alternating upright red and oblique green checkerboards. After adaptation, vertical and horizontal gratings appeared pink and oblique gratings appeared green. The results show an orientation and spatial frequency selectivity predicted by two-dimensional Fourier analysis.
