Fig. 1From: A robust anisotropic diffusion filter with low arithmetic complexity for imagesComparison of a noisy image, b PM as a smoother at n = 5, c FORADF as a smoother at n = 5, d FORADF at n = 25, and e the spreading effect in PM. Noisy image a is corrupted with Gaussian noise of variance 0.1. n represents the number of iterations. The dark patches indicate the spreading effect in PM algorithmBack to article page
