<H2>Description</H2>
<div class="H2">
<p>
<span class="fun">mmcbisector</span> creates the binary image
<code>y</code> by performing a filtering of the morphological skeleton of the binary image
<code>f</code>, relative to the structuring element
<code>B</code>. The strength of this filtering is controlled by the parameter n. Particularly, if
<code>n=0</code>,
<code>y</code> is the morphological skeleton of
<code>f</code> itself.
