Minima imposition on
<code>g</code> based on the marker
<code>f</code>.
<span class="fun">mminpos</span> creates an image
<code>y</code> by filing the valleys of
<code>g</code> that does not cover the connect components of
<code>f</code>. A remarkable property of
<code>y</code> is that its regional minima are exactly the connect components of
<code>g</code>.
