Class ThresholdConfidence

Object
AnchorBean<ReduceElements<ObjectMask>>
ReduceElements<ObjectMask>
ThresholdConfidence
public class ThresholdConfidence extends ReduceElements<ObjectMask>
Combines object-masks by projecting the maximum confidence-level for each voxel and thresholding.

After thresholding, a connected-components algorithm splits the thresholded-mask into single-objects.

Depending on the number of objects, two types of projection occur:

  • the projection occurs globally on an identically sized image to the entire size (more efficient for a larger number of objects and/or small image), or
  • using an R-Tree clusters of intersecting boxes are found, and each is processed separately (more efficient for a smaller number of objects and/or large image).
