Institute of Electrical and Electronics Engineers (IEEE)Camarena Estruch, JG.; Gregori Gregori, V.; Sapena Piera, A. (2013) Abstract-Mixed impulsive and Gaussian noise reduction from digital colour images is a challenging task because it is necessary to appropriately process both types of noise that in turn need to be distinguished from the original image structures such as edges and details. Fuzzy theory is useful to build simple, efficient and effective solutions for this problem. In this paper, we propose a fuzzy method to reduce Gaussian and impulsive noise from colour images. Our method uses one only filtering operation: a weighted averaging. A fuzzy rule system is used to assign the weights in the averaging so that both noise types are reduced and image structures are preserved. We provide experimental results to show that the performance of the method is competitive with respect to state-of-the-art filters.
