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

Use Cases, Examples

  • 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

  • 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)
