="rect" href="tut.sift">SIFT detector</a>, the MSER
algorithm extracts from an image <code/>I</code> a number of co-variant
regions, called MSERs. An MSER is a <em>stable</em> connected
component of some level sets of the image <code/>I</code>. Optionally,
elliptical frames are attached to the MSERs by fitting ellipses to the
regions. For a more in-depth explanation of the MSER detector, see
our <a shape="rect" href="../api/mser_8h.html">API reference for
MSER</a></p>
