Geometrical Optical Illusion via Sub-Riemannian Geodesics in the Roto-Translation Group
Benedetta Franceschiello, Alexey Mashtakov, Giovanna Citti +1
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 st…
A neuro-mathematical model for size and context related illusions
Benedetta Franceschiello, Alessandro Sarti, Giovanna Citti
We provide here a mathematical model of size/context illusions, inspired by the functional architecture of the visual cortex. We first recall previous models of scale and orientati…
Sub-Riemannian mean curvature flow for image processing
Giovanna Citti, Benedetta Franceschiello, Gonzalo Sanguinetti +1
In this paper we reconsider the sub-Riemannian cortical model of image completion introduced by Sarti and Citti in 2003. This model combines two mechanisms, the sub-Riemannian diff…
