Anti-aliasing filter - Wikipedia, the free encyclopedia Often, an anti-aliasing filter is a low-pass filter; however, this is not a requirement. Generalizations of the Nyquist–Shannon sampling theorem allow sampling of other band-limited passband signals instead of baseband signals. For signals that are bandwi
Matlab Tutorial : Digital Image Processing 6 - Smoothing : Low pass filter - 2014 Here is the script: I = imread('cameraman.tif'); J = imnoise(I,'salt & pepper',0.02); K = medfilt2(J); subplot(121);imshow(J); subplot(122);imshow(K); Much better. Unlike the previous filter which is just using mean value, this time we used median. Median
