trait RegistrationMetric[D] extends AnyRef

The basic interface for defining a metric for the scalismo registration framework. It is independent of the object representation that is used. The main assumption is that the objects are subject to a parametric transformation, and we can obtain for each fixed value of the parameters compute the value of the metric and a derivative.

Abstract Value Members

  1. abstract def derivative(parameters: DenseVector[Double]): DenseVector[Double]

    Computes the derivative of the metric at the point given by the parameters.

  2. implicit abstract def ndSpace: NDSpace[D]
  3. abstract def transformationSpace: TransformationSpace[D]
  4. abstract def value(parameters: DenseVector[Double]): Double

    Computes the metric value for the given parameter vector

  5. abstract def valueAndDerivative(parameters: DenseVector[Double]): ValueAndDerivative

    Computes value and derivative in one go.

    Computes value and derivative in one go. It should be the same as calling value and takeDerivative separately, but allows for more efficient implementations.
