Class MeanCurvatureForce2D

java.lang.Object
  edu.jhu.cs.cisst.algorithms.segmentation.gac.ActiveContourForce2D
      edu.jhu.cs.cisst.algorithms.segmentation.gac.MeanCurvatureForce2D

public class MeanCurvatureForce2D
extends ActiveContourForce2D

The Class MeanCurvatureForce2D moves the level set according to mean curvature. Mean curvature is defined as the divergence of the level set normal. For numerical stability, the magnitude of the Mean curvature is bounded from above.
