Topology-preserving smoothing of retinotopic maps
Fig 8
Smoothing results for the synthetic data: (A)-(D) are the results with PSNR = 10 for (A) Average smoothing, (B) Median smoothing, (C) Laplacian smoothing, and (D) proposed topological smoothing; (E)-(H) are the results with the same order as (A)-(D) but with PSNR = 5.
