<div>Image preprocessing. Step  1: the first row shows the SE type of a diamond; from left to right, the scale is 5, 10, and 15. The second row shows the SE type of a disk; from left to right, the scale is 5, 10, and 15. The last row shows the SE type of a line (scale 15); from left to right, the slope angle is 0.25<i>π</i>, 0.5<i>π</i>, and 0.75<i>π</i>.</div>
