From Wikipedia, the free encyclopedia
The Chubb illusion is an optical illusion wherein the apparent contrast of an object varies dramatically, depending on the context of the presentation.[1] Low-contrast texture surrounded by a uniform field appears to have higher contrast than when it is surrounded by high-contrast texture. This was observed and documented by Charles Chubb and colleagues in 1989.[2] An empirical explanation of the Chubb illusion was elucidated by Lotto and Purves in 2001.[1]
