Severe pollution of salt-and-pepper noise with high probability in digital images is widespread
such as to eliminate less information and noisy noise has many difficulties.Although light pollution of salt-and-pepper noise with low probability in digital images can be completely removed
it lacks of universal sense in actual image restoration.In this paper
aimed at the fuzzy partition in the gray-value spaces and fuzzy numbers describing the gray-value level
the extreme value method is used to conduct the noise with the high probability test and establish the suitable filtering window.And then
applying the defuzzification method of center of generalized gravity and the membership functions corresponding to the non-noise points to design a kind of new filter.Finally
we obtain that the filter can effectively filter the salt and pepper noise with high probability in digital images by simulation example
and its denoising performance is superior to other common filters.
