Topology-preserving smoothing of retinotopic maps

Visual area boundary delineation of the V1/V2/V3 complex of the first observer.
The colors of the surface represent manually labeled visual areas from the average data. The purple curves indicate boundaries between visual areas of V3d/V2d/V1d/V1v/V2v/V3v (from up to down), respectively. The green curves are eccentricity contours. (A) boundaries inferred from the raw data, and (B)-(E) boundaries after average, median, Laplacian, and topological smoothing.
