<p><b>Abstract</b>—In an earlier paper, Chen and Yan presented a theorem concerning zero crossings of boundary curvature under morphological openings. In this correspondence, we show by means of a counterexample a problem with this theorem and suggest how the theorem may be modified to make it correct.</p>
