Fig. 6From: A robust anisotropic diffusion filter with low arithmetic complexity for imagesPerformance of FORADF (λ = 1) for very high-density mixed noise a at n = 5 and b n = 25. λ represents the control parameter, and n represents the number of iterations. The results are given for very high-density mixed noise, i.e., Gaussian noise of variance 0.1 plus salt and pepper noise of density 90%Back to article page
