In this work,a new filter approach for removal of mixed noise based on rough set is proposed for the image that is usually corrupted by different noise simultaneously.In this algorithm,rough set theory is applied to image filtering,noise pixels can be separated based on the partitions of equivalent relation.According to the degree of noise interference,different filter algorithm could be chosen.Experimental results show that the proposed filter out performs median filter and mean filter,not only can provide better performance of suppressing noise but preserve more detail features.
