/** \class ShapePriorMAPCostFunctionBase
* \brief Represents the base class of maximum aprior (MAP) cost function used
* ShapePriorSegmentationLevelSetImageFilter to estimate the shape paramaeters.
*
* This class follows the shape and pose parameters estimation developed in [1].
*
* This class has two template parameters, the feature image type representing the
* edge potential map and the pixel type used to
* represent the output level set in the ShapePriorSegmentationLevelSetImageFilter.
