Detailed Description

template<class TImage>
class itk::StatisticsOpeningLabelMapFilter< TImage >

remove the objects according to the value of their statistics attribute

StatisticsOpeningLabelMapFilter removes the objects in a lavbel collection image with an attribute value smaller or greater than a threshold called Lambda. The attributes are the ones of the StatisticsLabelObject.

virtual::itk::LightObject::Pointer itk::StatisticsOpeningLabelMapFilter< TImage >::CreateAnother ( void ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::ShapeOpeningLabelMapFilter< TImage >.

template<class TImage >

void itk::StatisticsOpeningLabelMapFilter< TImage >::GenerateData ( void )

protectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling ThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead.
