The Ehrenstein illusion

Abstract : The original Ehrenstein illusion was first described by Walter Ehrenstein senior (Ehrenstein, 1941, 1954). It is generated by a configuration of four line segments which induce the perception of a so-called illusory figure at the centre of the configuration (Fig 1a). This illusion is part of a class of visual perceptual phenomena referred to as contrast or brightness illusions, as explained in detail in this state-of-the-art review.
