A novel image noise reduction technique based on hysteresis processing

In this paper a new method based on hysteresis phenomena for image noise suppression has been presented. First, the basic procedures of hysteresis processing are described and then two new proposed approaches namely, local hysteresis smoothing (LHS) and local adaptive hysteresis smoothing (LAHS) procedures are presented. In these procedures, we attempted to propose a principled way to compute the best setup of the proposed hysteresis smoothing method in the presence of Additive White Gaussian Noise (AWGN). The results of the proposed approaches are compared in both objective and subjective manners with the other noise suppression methods in the presence of different levels of noise. The experimental results showed the feasibility of the proposed approaches denoising ability. (C) 2015 Elsevier GmbH. All rights reserved.
