Performance of FORADF in terms of PSNR for various λ values at 20% salt and pepper noise density for n = 5. λ represents the control parameter, and n represents the number of iterations. The figure shows the stability of FORADF for various λ values, and the performance is measured in terms of the performance metric PSNR. : performance of FORADF for Cameraman image. : performance of FORADF for Lena image. : performance of FORADF for Pepper image.
