Hello Experts,
I am trying to build the median filter with given window size. Here is what I did so far, please correct me because for some reason I don't get the right results for general rows and cols (non equal or equal):
function [ newImg ] = myMedian( img, rows, cols )
ModifyImg = padarray(img,[(abs(rows-cols)+1) (abs(rows-cols)+1)]);
newImg = zeros(size(img));
for i = 1:(size(ModifyImg,1) - 2*(abs(rows-cols)+1))
for j = 1:(size(ModifyImg,2) - 2*(abs(rows-cols)+1))
window = ModifyImg(i:i+rows-1, j:j+cols-1);
Sorted_Window = sort(window(:));
newImg(i,j) = Sorted_Window(ceil(0.5*rows*cols));
end
end
