Abstract:

The distortions of visual perception in the classical Wundt-Hering illusion (the illusion of the fan) and its modified version were evaluated, as well as those in the Oppel-Kundt illusion. The line curvature was found to be perceived identically for continuous lines and lines interpolated over the points of intersection with the fan. The dependence of the Oppel-Kundt illusion on the number of lines filling the interval turned out to be invariant with respect to the size of the spatial interval. The results were approximated by mathematical models, which are based on the low-frequency filtering of images, taking into account the concept of selective attention in the process of visual perception as well as image processing by receptive fields, known as spatial frequency filters, combined into modules.

Keywords:

Wundt-Hering illusion, Oppel-Kundt illusion, centroid, spatial frequency analysis, model of modules
