Segmentation Usage

Geodesic Segmentation

The geodesic distance based segmentation is a semi-automatic technique to generate masks for specific tissue types.

REQUIREMENTS:

A single image with distinct boundaries for tissue needing to be segmented. [1]

USAGE:

ITK-SNAP

ITK-SNAP is a stand-alone software application used to segment structures in 3D medical images and other utilities. Within CaPTk specifically, ITK-SNAP is tightly integrated as a tool used for segmentation, accepting files chosen through the CaPTk interface and returning results for further use within CaPTk. ITK-SNAP uses a combination of random forests and level sets to obtain very precise segmentations of generic tissues [2].
