/** \class ShapeLabelMapFilter
* \brief The valuator class for the ShapeLabelObject
*
* ShapeLabelMapFilter can be used to set the attributes values of the
* ShapeLabelObject in a LabelMap.
*
* ShapeLabelMapFilter takes an optional parameter, used only to
* optimize the computation time and the memory usage when the
* perimeter or the feret diameter is used: the exact copy of the
* input LabelMap is stored in an Image.
* It can be set with SetLabelImage(). It is cleared at the end of the
* computation, so must be reset before running Update() again. It is
* not part of the pipeline management design, to let the subclasses
* of ShapeLabelMapFilter use the pipeline design to specify truly
* required inputs.
