sliding-window

The upper bounds of your for-loops are the cause for your troubles. You specify: imh=size(ab,2); imw=size(ab,1); However, your for-loops have these conditions: j=1:imh+wh-1 and i=1:imw+ww-1 So you move past both the ‘height’ and the ‘width’ dimension. Try this instead: for j=1:imh-wh for i=1:imw-ww w1=ab(j:j+wh,i:i+wh,:); w2=salt(j:j+wh,i:i+wh,:); w3=w1-w2; end k=k+1; end 1 solved How to apply sliding … Read more
