Abstract
Removal of Mixed noise from digital color images is a challenging task because it requires processing of different types of noise. Also, noise need to be distinguished from the original image structures such as edges and details. Fuzzy theory is an effective solution to this problem. In this paper, a new fuzzy method is proposed to reduce impulse and Gaussian noise from color images. A weighted averaging filtering operation is used for this purpose. The weights in the averaging process are assigned using a fuzzy rule system based on a new certainty function, so as to reduce both noise types and to preserve image structures. Experimental results show that the method outperforms the state-of-the-art filters.
