Geometrical Optical Illusion via Sub-Riemannian Geodesics in the Roto-Translation Group

19 Feb 2020 Franceschiello Benedetta Mashtakov Alexey Citti Giovanna Sarti Alessandro

We present a neuro-mathematical model for geometrical optical illusions (GOIs), a class of illusory phenomena that consists in a mismatch of geometrical properties of the visual stimulus and its associated percept. They take place in the visual areas V1/V2 whose functional architecture have been modelled in previous works by Citti and Sarti as a Lie group equipped with a sub-Riemannian (SR) metric...
