Multiplicative noise,unlike the standard Gaussian additive noise,often appears in synthetic aperture radar and sonar and laser imaging.The multiplicative noise agrees with Rayleigh and Gamma functions.This paper converts the multiplicative model into an additive one by taking logarithms,changes the standard TV regularizer into an adaptive fidelity term diffusion model and applies mathematical models into multiplicative imaging denoising.The model can not only remove noise but also enhance edges.
