Re: Median image

"Tomas Fridrich" I think you'd have to reshape them into a column vector, then stitch all three together, like this: newImage = [image1(:), image2(:), image(3)]; Then call medfilt2() to take the median...

Re: median filtering ignoring NaN

Here is code which finds the median of just the finite values. Then, it backfills the nan values. uMed(find(isfinite(u))) = medfilt1(u(isfinite(u)),100); uMed(find(~isfinite(u))) = nan; "Alex "...

Re: median filtering ignoring NaN

Here is the function that can use with large array as it process by blocks function M = mediannan(A, sz) % M = mediannan(A, sz) % A is 2D array % sz is block size, 1 or 2 elements if nargin<2    sz...

Re: median filtering ignoring NaN

This latest version remove one more big preallocation, so it's even safer for memory function M = mediannan(A, sz) % M = mediannan(A, sz) % A is 2D array % sz is block size, 1 or 2 elements if...
