Module Description

This module uses a single seed point to segment an image. The seed point (fiducial) is placed within the region to be segmented. The upper and lower thresholds are entered by the user. The segmented region will contain pixels that are connected to this seed, and lie in between this range. Multiple seed points can be used.

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.
