Fig. 6From: Orientation Maps in V1 and Non-Euclidean GeometryAn orientation map on the sphere sampled from the argument of a monochromatic \(\mathit{SO}(3)\)-invariant Gaussian random field on the sphere with spin 7. We plotted the restriction to a hemisphere; we used a superposition of spherical harmonics with spin seven and random, reduced independent Gaussian weightsBack to article page
