<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->

<p><em>Affine adaptation</em> is the process of estimating the
affine shape of an image region in order to construct an
affinely co-variant feature frame. This is useful in order to
compensate for deformations of the image like slant, arising for
example for small perspective distortion.</p>

<p>To switch on affine adaptation, use
the <code/>EstimateAffineShape</code> option:</p>
