Module Description

This Python module takes in input a surface and labels it according to surface connectivity. The module either labels the surface with a different RegionId for each connected region, or it extracts the connected region closest to an input fiducial. Optionally, the module produces a list of fiducials positioned on each connected region and labeled with its RegionId.

Usage

Examples, Use Cases & Tutorials

• The module is appropriate when there is need of extracting different disconnected components of a model or label them.
• For developers: the module is a good example on how Python CLI modules can access and modify the MRML scene (unlike executable and shared library CLI modules)

Quick Tour of Features and Use

List all the panels in your interface, their features, what they mean, and how to use them. For instance:

• Surface Connectivity Parameters:
  • Connectivity mode: choose between assigning a RegionId to each connected region (AllRegions) or extract the connected region closest to a seed fiducial (ClosestToSeed).
  • Enable output fiducials: enable output of a fiducial list containing one fiducial per connected region labeled with the corresponding RegionId
• IO:
  • Input Surface: the input surface
  • Output Surface: the labeled surface (for AllRegions mode) or the labeled portion of the surface closest to the seed (for ClosestToSeed)
