Individuation of 3D perceptual units from neurogeometry of binocular cells
Maria Virginia Bolelli, Giovanna Citti, Alessandro Sarti +1
We model the functional architecture of the early stages of three-dimensional vision by extending the neurogeometric sub-Riemannian model for stereo-vision introduced in \cite{BCSZ…
Cortical Functional architectures as contact and sub-Riemannian geometry
Giovanna Citti, Alessandro Sarti
In a joint paper, Jean Petitot together with the authors of the present paper described the functional geometry of the visual cortex as the symplectization of a contact form to des…
A model of reaching via subriemannian geodesics in Engel-type group
Caterina Mazzetti, Alessandro Sarti, Giovanna Citti
In this paper, we propose a model of arm reaching movements expressed in terms of geodesics in a sub-Riemannian space. We will choose a set of kinematic variables to which motor co…
Good continuation in 3D: the neurogeometry of stereo vision
Maria Virginia Bolelli, Giovanna Citti, Alessandro Sarti +1
Classical good continuation for image curves is based on position and orientation. It is supported by the columnar organization of cortex, by psychophysical experiments, and b…
A framework for stereo vision via optimal transport
Mattia Galeotti, Alessandro Sarti, Giovanna Citti
We present a theoretical framework for a stereo vision method via optimal transport tools. We consider two aligned optical systems and we develop the matching between the two pictu…
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…
