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…
A neuro-mathematical model for geometrical optical illusions
B. Franceschiello, A. Sarti, G. Citti
Geometrical optical illusions have been object of many studies due to the possibility they offer to understand the behaviour of low-level visual processing. They consist in situati…
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…
