      public AssociatedPair()
    • AssociatedPair

      public AssociatedPair​(double x1, double y1, double x2, double y2)
      Creates a new associated point from the two provided points.
      Parameters:
      x1 - image 1 location x-axis.
      y1 - image 1 location y-axis.
      x2 - image 2 location x-axis.
      y2 - image 2 location y-axis.
    • AssociatedPair

      public AssociatedPair​(Point2D_F64 p1, Point2D_F64 p2)

    • AssociatedPair

      public AssociatedPair​(Point2D_F64 p1, Point2D_F64 p2, boolean newInstance)
      Allows features to either be copied or saved as references.
      Parameters:
      p1 - image 1 location
      p2 - image 2 location
      newInstance - Should it create new points or save a reference to these instances.
