52 /** \brief TransformationValidation represents the base class for methods
53 * that validate the correctness of a transformation found through \ref TransformationEstimation.
54 *
55 * The inputs for a validation estimation can take any or all of the following:
56 *
57 * - source point cloud
58 * - target point cloud
59 * - estimated transformation between source and target
60 *
61 * The output is in the form of a score or a confidence measure.
62 *
63 * \note The class is templated on the source and target point types as well as on the output scalar of the transformation matrix (i.e., float or double). Default: float.
