    • transform

      public void transform(double[] x, double[] y)
      Description copied from class: Transformer
      Convert a single point where the output vector is supplied.
      Specified by:
      transform in class Transformer
      Parameters:
      x - The input vector.
      y - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.

    • preserves

      protected boolean preserves()

    • inverse

      public Distorter inverse()
      The inverse Distorter (i.e., the undistorter) uses much of the same machinery, so we generate it as a inner class of the distorter.
      Specified by:
      inverse in class Distorter

    • isInverse

      public boolean isInverse(Transformer t)
      Is this the inverse of another distorter?
      Specified by:
      isInverse in class Transformer
