Webis used instead of the median. ZZxymean= (4) Weighted filtering: The weighted median filtering is to multiply each pixel in the window by a corresponding weight, and then … WebAnd any explanation of cases where weighted median is strongly recommended to be used. Median Filter replaces pixel value c with p where p is the median of pixel values in neighborhood of c. In the case of weighted median there are N $\left[ I_1,I_2,..,I_N \right]$ neighbor pixels,for each pixel there is also weight.
