WebAug 1, 1996 · Grating induction ( McCourt, 1982) is a brightness illusion in which an illusory (induced) sinewave grating is seen within a physically homogeneous test field … WebJun 1, 1994 · The magnitude of brightness variations within test fields of grating induction and phantom grating type displays was measured using a pointwise brightness matching paradigm. A range of test field luminances was sampled which encompassed those reported to give rise to both in-phase phantom and counterphase induced gratings.

WebThe experiments explore whether the mechanism(s) underlying grating induction (GI) can also account for simultaneous brightness contrast (SBC). At each of three test field heights (1, 3 and 6 deg), point-by-point brightness matches were obtained from two subjects for test field widths of 32 deg (GI condition), 14, 12, 8, 6, 3 and 1 deg.

WebOne suggested explanation for geometrical illusions is that they arise as a result of “errors” in the early processing of visual information ( Von der Heydt, 2014 ). The visual system must deal with the uncertainty generated by the noise that is inherent in the processing of visual stimuli in order to extract meaningful information about the world.
