Module Description

This module uses two seed points to segment an image. One seed point (fiducial) is placed within the region to be segmented, and the other is placed outside that region. Multiple seed points can be used as well. The lower threshold is given as an input by the user. The isolated connected image filter will find the isolating upper threshold. If no isolating threshold can be found then the segmentation will fail.

Use Cases

This module is meant to be used for segmenting the entire endocardium region from a cardiac MRI or MRA image. It can also be used for segmentation of structures in other types of images.
