<p>Also, the warning <code>[WARN ] No extension given with filename ''; type unknown.  Save failed.</code> is caused by line 52 in <code>mean_shift_main.cpp</code>:</p>

<p><code>const double bandwidth = CLI::GetParam&lt;double&gt;("bandwidth");</code></p>

<p>That variable isn't used, and isn't documented as a <code>PARAM_DOUBLE()</code> macro.  My guess is that the line isn't necessary. :)</p>
