<pre>
The `fd_bounding_poly` bounding polygon is tighter than the
`boundingPoly`, and encloses only the skin part of the face. Typically, it
is used to eliminate the face from any image analysis that detects the
"amount of skin" visible in an image. It is not based on the
landmarker results, only on the initial face detection, hence
the &lt;code&gt;fd&lt;/code&gt; (face detection) prefix.
