- Abstract
According to the fact that conventional color image filtering algorithms do not distinguish whether the pixels in the sliding window are noise pixels and thus leading to poor filtering results, this paper proposed a switching vector median filtering method based on fuzzy decision. Firstly, it used the switching conditions to determine whether the center pixel of a neighborhood was noisy. For the corrupted pixels in color image, it constructed a membership function for removal of noise pixels according to fuzzy mathematical theory, estimated all the pixels' memberships in the sliding window according to the proposed membership function. And then it removed some pixels with high membership in terms of the confidence interval. Finally, it employed VMF in the optimized sliding window. Compared with the existing method, the novel method could improve the filtering results by removing the suspected noise pixels in the sliding window. Experimental results show that the proposed method performs better performance of robustness and practicality.
