Fig. 5From: A robust anisotropic diffusion filter with low arithmetic complexity for imagesPerformance of a RF (λ = 0.25), b AMD (λ = 0.25), c AADF (λ = 0.25), d FORADF (λ = 0.25), and e FORADF (λ = 1) for high-density mixed noise. λ represents the control parameter, and n represents the number of iterations. The results are given for high-density mixed noise, i.e., Gaussian noise of variance 0.1 plus salt and pepper noise of density 70%Back to article page
