In this paper, we propose distance-based mean filter (DBMF) to remove the salt and pepper noise. Although DBMF also uses the adaptive conditions like AMF, it uses distance-based mean instead of median. The distance-based mean focuses on similarity of pixels based on distance. glory fellowship jasper al

"WebAug 2, 2024 · The filtering process is to move the filter point-by-point in the image function f (x, y) so that the center of the filter coincides with the point (x, y). At each point (x, y), the filter’s response is calculated based on the specific content of the filter and through a predefined relationship called ‘template’. " - Mean filtering in image processing
