Grating induction is a brightness/lightness illusion in which a sinewave luminance grating induces the appearance of a counterphase sinusoidal grating in a homogeneous test field oriented orthogonally to the inducing grating. Induction is greatest at low spatial and temporal frequencies and declines with increasing frequency in both dimensions. Induction magnitude also declines with increasing test field height and scales as the product of inducing grating spatial frequency (c/d) and test field height. These properties of grating induction are difficult to explain using nonfiltering-based models but are readily accounted for by multiscale spatial filtering and lend support to such models of brightness/lightness induction.

Keywords:   grating induction, brightness contrast, brightness/lightness induction, multiscale spatial filtering, spatial frequency, temporal frequency
