Class SoInfluenceZonesProcessing

  • All Implemented Interfaces:

    public class SoInfluenceZonesProcessing
    extends SoImageVizEngine
    SoInfluenceZonesProcessing engine. The SoInfluenceZonesProcessing engine computes the skeleton by Influence Zone (SKIZ).

    For an introduction, see section :

    • Morphology
    • Skeletonization

    Skeletonization is used to produce a simplified representation of the objects in an image, while preserving their geometrical structure. The representation may then be used to calculate length, direction, etc. or to detect special topological structures such as end or triple points (number of crossings). Skeletonization is a transformation based on the thinning of connected components until a line is achieved.

    This engine produces a pruned skeleton of the background. The influence zone of a particle X is the set of points closer to X than to any other particle Y. The skeleton by influence zones is the boundary splitting the different influence zones, and it separates the image into zones surrounding each object.

    Skeleton by influence zones This engine searches the skeleton of a binary or labelled image by influence zones. If the input is a binary image, it is first labelled, then the influence zones are determined by successive conditional dilations. The process stops as soon as all the zones are hitting each other.
