<br />
===Quick Tour of Features and Use===<br />
<br />
IntensitySegmenter is a simple tool that segments an image according to intensity value. It is mainly used to segment CT scans using the [http://en.wikipedia.org/wiki/Hounsfield_scale Hounsfield scale] but the ranges of intensities and their corresponding labels can be specified in an input text file.<br />
<br />
A list panels in the interface, their features, what they mean, and how to use them.<br />

* <span style="color:blue">'''''Parameters'''''</span>: <br />
** <span style="color:green">'''inputFile'''</span> [<span style="color:orange">--inputFile</span>] [<span style="color:pink">-i</span>]: Input Image <br />
** <span style="color:green">'''outputFile'''</span> [<span style="color:orange">--outputFile</span>] [<span style="color:pink">-o</span>]: Output Image<br />
** <span style="color:green">'''rangeFile'''</span> [<span style="color:orange">--rangeFile</span>] [<span style="color:pink">-r</span>]: Input range file used to segment the image. If not specified, uses a default hard coded range that can be saved in a text file using the following option --saveDefaultRangeFile<br />
** <span style="color:green">'''saveDefaultRangeFile'''</span> [<span style="color:orange">--saveDefaultRangeFile</span>] [<span style="color:pink">-s</span>]: Save example range file containing 8 labels: air, lungs, soft tissue, fat, water, CSF, blood and muscle, cancellous bone, dense bone. More information about threshold can be found [http://en.wikipedia.org/wiki/Hounsfield_scale here]<br />
** <span style="color:green">'''defaultLabelValue'''</span> [<span style="color:orange">--defaultLabelValue</span>] [<span style="color:pink">-d</span>]: Sets the label value of voxels for which no value is specified in the range file<br />
|}<br />
<br />
Example of a range file:<br />
<pre><br />
-infty 45 0<br />
45 700 8<br />
700 +infty 9<br />
</pre><br />
The first and second values on each line are the minimum and maximum intensities for the corresponding label specified as the third value on each line.<br />
