WebThe filter2 function filters data by taking the 2-D convolution of the input X and the coefficient matrix H rotated 180 degrees. Specifically, filter2(H,X,shape) is equivalent to conv2(X,rot90(H,2),shape) . WebAug 21, 2012 · A 1 by 3 median filter was what I was thinking at first but it's such a perfectly symmetrical checkerboard that I don't think a median filter will work. A little more accuracy could be gotten using a sigma filter (since that won't replace "good" pixels that should be left alone like a median filter will), but since median filter is built in, I ...
