Abstract
The non-local (NL) averaging method for image de-noising was recently introduced. The method shows very good filtering properties for additive Gaussian distributed noise. However, the performances of the NL averaging method for non-Gaussian, especially impulsive, noise is not satisfactory. In this paper, we propose a novel filtering scheme, called nonlinear non-local (NLNL) averaging that has better performances in mixed (Gaussian and impulsive) noise environments. Experiments comparing the performances of the NL, NLNL and other related approach are presented
