Interface LandmarkServices

public interface LandmarkServices
Public stateless services dealing with landmarks. TO DO: Provide IcpTransformation instead of PrTransformation?

  • Method Details

    • getProcrustesTransformation

      static PrTransformation getProcrustesTransformation(Collection<Landmark> staticFaceFPs, Collection<Landmark> transformedFaceFPs, boolean scale)
      Computes and return transformation that registers landmarks from the second face the first face.
      Parameters:
      staticFaceFPs - Feature points of a face towards which the superimposition is performed. Must not be null.
      transformedFaceFPs - Feature points of a face to be transformed (superimposed). Must not be null.
      scale - Whether to scale the face as well
      Throws:
      IllegalArgumentException - if there are not at least three common feature points in the faces

    • transform

      static <T extends IPosition> void transform(List<T> points, PrTransformation transformation)
      Applies transformation to given points.
      Type Parameters:
      T - Point type, e.g., MeshPoint, Landmark, etc.
      Parameters:
      points - Points to be transformed
      transformation - Transformation

    • computeSymmetryPlane

      static Plane computeSymmetryPlane(Collection<Landmark> landmarks)
      Calculation of symmetry plane from landmarks. Only landmarks with "_L" and "_R" suffix in their code are taken into account.
      Parameters:
      landmarks - Landmarks
      Returns:
      Symmetry plane
