The geodesic distance transform based segmentation is a semi-automatic technique to delineate structures of distinct intensity.
REQUIREMENTS: A single image with distinct boundaries for the structure that needs to be segmented. [1]
USAGE:
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 precise segmentations of structures [2].
