Quick Tour of Features and Use

IntensitySegmenter is a simple tool that segments an image according to intensity value. It is mainly used to segment CT scans using the Hounsfield scale but the ranges of intensities and their corresponding labels can be specified in an input text file.

A list panels in the interface, their features, what they mean, and how to use them.

Parameters: inputFile [--inputFile] [-i]: Input Image outputFile [--outputFile] [-o]: Output Image rangeFile [--rangeFile] [-r]: 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 saveDefaultRangeFile [--saveDefaultRangeFile] [-s]: 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 here defaultLabelValue [--defaultLabelValue] [-d]: Sets the label value of voxels for which no value is specified in the range file

Example of a range file:

-infty 45 0
