Abstract
Detaching of the test objects from the inducing background was found to reduce significantly Adelson’s “snake” lightness illusion but not grating induction. Moreover, the same grating induction effect was measured from 3D real cylinders and a 2D sinewave grating. We conclude that grating induction and Adelson’s snake lightness illusion are different types of simultaneous lightness contrast.
