Abstract:
We introduce a natural spherical extension of a well-known contour perception model due to J. Petitot, G. Citti
and A. Sarti, which additionally takes into account the spherical nature of the retina.
Such a spherical extension was initially proposed by U. Boscain and F. Rossi. We extend their model by
taking into account a relevant anisotropy parameter controlling the stiffness of optimal spherical contours, and an external cost modeling the non-uniform distribution of photoreceptors on the retina.
Key words and phrases:
association field, visual cortex, cortical magnification, sub-Riemannian geodesics, Lie group $\mathrm{SO(3)}$.
