A cortical-inspired sub-Riemannian model for Poggendorff-type visual illusions
Emre Baspinar, Luca Calatroni, Valentina Franceschi +1
We consider Wilson-Cowan-type models for the mathematical description of orientation-dependent Poggendorff-like illusions. Our modelling improves two previously proposed cortical-i…

A cortical-inspired model for orientation-dependent contrast perception: a link with Wilson-Cowan equations
Marcelo Bertalmío, Luca Calatroni, Valentina Franceschi +2
We consider a differential model describing neuro-physiological contrast perception phenomena induced by surrounding orientations. The mathematical formulation relies on a cortical…
