Topology-preserving smoothing of retinotopic maps
Fig 14
Smoothing is robust to the inaccurate interior boundary: (A) the raw visual polar angle v(2) is rendered on the parametric unit disk (i.e., radius is one), (B) v(2) as a function on the cropped region, (C) visual polar angle v(2) along the white arc by topological smoothing, (D) similar result as (C) but the curve is from Laplacian smoothing.
