Numerical simulation of modified Perona-Malik equantion in digital image denoising applications

Abstract


Classical Perona-Malik model is modified and adapted for digital color image filtering. An advantage of the proposed scheme is the use of perceptual color difference metrics to measure the distance between pixels, and the modification of diffusion coefficients calculation formulas. Numerical simulation shows that the proposed scheme has a high quality and performance.
