Class SoSieveLabelingProcessing

    SafeDisposable
    public class SoSieveLabelingProcessing
extends SoImageVizEngine
    SoSieveLabelingProcessing engine produces a new label image by grouping labels of the input label image. For an introduction, see:
    • section Image Analysis
    • Measure Node

    The SoSieveLabelingProcessing engine produces a new label image by grouping labels of the input label image. Labels are grouped according to to a list of sieve values that defines input ranges for each output label value.

    Figure 1: Label grouping based on a sieve First, the field Measure selects the measure that will be used to group label. Then each label of the input analysis will be assigned to an output group depending on the value of the selected measure. The figure (Figure 1) presents an example of the label grouping procedure that is described in details below:

    • A label whose measure lies in between 2 sieve values is assigned to the same id. For instance all labels which lie in between value-1 and value-2 will be assigned to the label 1.
      • Labels whose measurement is less than the first sieve value are assigned to the exterior (i.e the label 0).
      • Labels whose measurement is greater than the last sieve value are assigned to the exterior (i.e the label is 0).
      • If there are N Sieve values, the output labels field will be composed of N-1 label.
