Detailed Description

SoExpandLabelsProcessing engine

The SoExpandLabelsProcessing engine performs an label expansion of an image.

For an introduction, see:

• section Morphology
• Introduction and definition for dilations

The label expansion cans be performed either with a REGIONS mode or an OBJECTS mode.

REGIONS mode

The engine performs an iterative dilation of a label image. It stops the process when the complete image is covered.

Figure 1: Example of label expansion with REGIONS mode

OBJECTS mode

The engine performs a constrained dilation of a label image. Its first aim is to expand labels obtained by using an SoMarkerBasedWatershedProcessing engine with CATCHMENT mode, so that all black pixels of the boundaries are filled with the value of the most present label among the height neighbors.

Figure 2: Example of label expansion with OBJECTS mode applied to the result of SoMarkerBasedWatershedProcessing engine with CATCHMENT mode
