<!---Data Types and Enumerations--->

<h3><a name="enumerations">Data Types and Enumerations</a></h3>

<p>The EDISON system parameters are either of integer or floating point type, or
they are an enumeration. Each enumeration as well as the <b>Vertex List</b> data
structure are outlined below.

<p><b><a name="flags">Flag</a></b>

<p>The flag enumeration is used to specify the system state. Flags have a value
of either ON or OFF and are set using <a href="#flagcommands">flag commands</a>.

<p><i>Possible Values</i>
<ul>
<li>ON</li>
<li>OFF</li>
</ul>

<p><b><a name="speedup">Speedup Level</a></b>

<p>The speedup level of the mean shift algorithm is determined through the use
of this enumeration. There are three speedup levels outlined below: (1) NONE
indicating that no speedup is to be used, (2) MEDIUM employs the speedup
technique described in the paper, and (3) HIGH is an extension of the MEDIUM
