Detailed Description

template<class TImage>
class itk::Statistics::ImageToHistogramFilter< TImage >

This class generates an histogram from an image.

The concept of Histogram in ITK is quite generic. It has been designed to manage multiple components data. This class facilitates the computation of an histogram from an image. Internally it creates a List that is feed into the SampleToHistogramFilter.

Member Function Documentation

template<class TImage >

void itk::Statistics::ImageToHistogramFilter< TImage >::AfterThreadedGenerateData ( void ) [protected, virtual]

If an imaging filter needs to perform processing after all processing threads have completed, the filter can can provide an implementation for AfterThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

template<class TImage >

void itk::Statistics::ImageToHistogramFilter< TImage >::BeforeThreadedGenerateData ( void ) [protected, virtual]

If an imaging filter needs to perform processing after the buffer has been allocated but before threads are spawned, the filter can can provide an implementation for BeforeThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

virtual::itk::LightObject::Pointer itk::Statistics::ImageToHistogramFilter< 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::Object.

template<class TImage >

virtual const char* itk::Statistics::ImageToHistogramFilter< TImage >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

template<class TImage >

const HistogramType* itk::Statistics::ImageToHistogramFilter< TImage >::GetOutput ( ) const

Return the output histogram.

template<class TImage >

HistogramType* itk::Statistics::ImageToHistogramFilter< TImage >::GetOutput ( )

Return the output histogram.

template<class TImage >

virtual void itk::Statistics::ImageToHistogramFilter< TImage >::GraftOutput ( DataObject * output ) [virtual]

Method that facilitates the use of this filter in the internal pipeline of another filter.

template<class TImage >

itk::Statistics::ImageToHistogramFilter< TImage >::itkSetGetDecoratedInputMacro	(	HistogramSize	,
		HistogramSizeType
	)

Methods for setting and getting the histogram size. The histogram size is encapsulated inside a decorator class. For this reason, it is possible to set and get the decorator class, but it is only possible to set the histogram size by value. This macro declares the methods SetHistogramSize(), SetHistogramSizeInput(), GetHistogramSizeInput().

template<class TImage >

itk::Statistics::ImageToHistogramFilter< TImage >::itkSetGetDecoratedInputMacro	(	MarginalScale	,
		HistogramMeasurementType
	)

Methods for setting and getting the Marginal scale value. The marginal scale is used when the type of the measurement vector componets are of integer type.

template<class TImage >

itk::Statistics::ImageToHistogramFilter< TImage >::itkSetGetDecoratedInputMacro	(	HistogramBinMinimum	,
		HistogramMeasurementVectorType
	)

Methods for setting and getting the Minimum and Maximum values of the histogram bins.

template<class TImage >

itk::Statistics::ImageToHistogramFilter< TImage >::itkSetGetDecoratedInputMacro	(	HistogramBinMaximum	,
		HistogramMeasurementVectorType
	)

Methods for setting and getting the Minimum and Maximum values of the histogram bins.

template<class TImage >

itk::Statistics::ImageToHistogramFilter< TImage >::itkSetGetDecoratedInputMacro	(	AutoMinimumMaximum	,
		bool
	)

Methods for setting and getting the boolean flag that defines whether the minimum and maximum of the histogram are going to be computed automatically from the values of the sample

template<class TImage >

DataObject::Pointer itk::Statistics::ImageToHistogramFilter< TImage >::MakeOutput ( DataObjectPointerArraySizeType idx ) [protected, virtual]

Make a DataObject of the correct type to used as the specified output. Every ProcessObject subclass must be able to create a DataObject that can be used as a specified output. This method is automatically called when DataObject::DisconnectPipeline() is called. DataObject::DisconnectPipeline, disconnects a data object from being an output of its current source. When the data object is disconnected, the ProcessObject needs to construct a replacement output data object so that the ProcessObject is in a valid state. So DataObject::DisconnectPipeline eventually calls ProcessObject::MakeOutput. Note that MakeOutput always returns a itkSmartPointer to a DataObject. ImageSource and MeshSource override this method to create the correct type of image and mesh respectively. If a filter has multiple outputs of different types, then that filter must provide an implementation of MakeOutput().

Reimplemented from itk::ProcessObject.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
