<div class="block">Maximally stable extremal region extractor
The class encapsulates all the parameters of the %MSER extraction algorithm (see [wiki
article](http://en.wikipedia.org/wiki/Maximally_stable_extremal_regions)).
<ul>
<li>
there are two different implementation of %MSER: one for grey image, one for color image
</li>
</ul>
<ul>
<li>
the grey image algorithm is taken from: CITE: nister2008linear ; the paper claims to be faster
than union-find method; it actually get 1.5~2m/s on my centrino L7200 1.2GHz laptop.
</li>
</ul>
<ul>
<li>
the color image algorithm is taken from: CITE: forssen2007maximally ; it should be much slower
than grey image method ( 3~4 times )
</li>
</ul>
<ul>
<li>
(Python) A complete example showing the use of the %MSER detector can be found at samples/python/mser.py
