/** \class SampleSelectiveMeanShiftBlurringFilter
* \brief This filter blurs the input sample data using mean shift
* algorithm selectively.
*
* The blurring process is identical to that of the
* SampleMeanShiftBlurringFilter except that users can specify which
* components of a measurement vector is affected by the blurring.
* The mean mode seeking behavior is not changed. The component
* selection affects only the generation of the final mode point. To
* specify the components to be blurred, users use the
* SetComponentSelections method. The size of the selection vector
* should be same as the size of a measurement vector. Only the
* components of the selection vector whose flag value is true will be
* blurred.
*
* <b>Recent API changes:</b>
* The static const macro to get the length of a measurement vector,
* \c MeasurementVectorSize has been removed to allow the length of a measurement
* vector to be specified at run time. Please use the function
* GetMeasurementVectorSize() instead. It is now obtained at run time from the
* sample set as input. The typedef for \c ComponentSelectionsType
* has changed from FixedArray to \c std::vector.
