Generation of tubular and membranous shape textures with curvature functionals

1 code implementation8 Mar 2021 Anna Song

Tubular and membranous shapes display a wide range of morphologies that are difficult to analyze within a common framework.

Spatial and color hallucinations in a mathematical model of primary visual cortex

no code implementations19 Oct 2021 Olivier D. Faugeras, Anna Song, Romain Veltz

We show that the model equation is equivariant with respect to the direct product G of the group of the Euclidean transformations of the planar lattice determined by the spatial periodicity and the group of color transformations, isomorphic to O(2), and study the equivariant bifurcations of its stationary solutions when some parameters in the model vary.
