Detailed Description

Compute the histogram for an image.

vtkImageHistogram generates a histogram from its input, and optionally produces a 2D black-and-white image of the histogram as its output. Unlike the class vtkImageAccumulate, a multi-component image does not result in a multi-dimensional histogram. Instead, the resulting histogram will be the sum of the histograms of each of the individual components, unless SetActiveComponent is used to choose a single component.

Thanks:: Thanks to David Gobbi at the Seaman Family MR Centre and Dept. of Clinical Neurosciences, Foothills Medical Centre, Calgary, for providing this class.

Reimplemented in vtkImageHistogramStatistics.

static int vtkImageHistogram::IsTypeOf ( const char * name )

static

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkThreadedImageAlgorithm.

Reimplemented in vtkImageHistogramStatistics.

virtual int vtkImageHistogram::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented in vtkImageHistogramStatistics.

static vtkImageHistogram* vtkImageHistogram::SafeDownCast ( vtkObject * o )

static

Reimplemented from vtkThreadedImageAlgorithm.

Reimplemented in vtkImageHistogramStatistics.

void vtkImageHistogram::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

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.

Reimplemented from vtkThreadedImageAlgorithm.

Reimplemented in vtkImageHistogramStatistics.

virtual void vtkImageHistogram::SetActiveComponent ( int )

virtual

Set the component for which to generate a histogram. The default value is -1, which produces a histogram that is the sum of the histograms of the individual components.

virtual int vtkImageHistogram::GetActiveComponent ( )

virtual

Set the component for which to generate a histogram. The default value is -1, which produces a histogram that is the sum of the histograms of the individual components.

virtual void vtkImageHistogram::SetAutomaticBinning ( int )

virtual

If this is On, then the histogram binning will be done automatically. For char and unsigned char data, there will be 256 bins with unit spacing. For data of type short and larger, there will be between 256 and MaximumNumberOfBins, depending on the range of the data, and the BinOrigin will be set to zero if no negative values are present, or to the smallest negative value if negative values are present. For float data, the MaximumNumberOfBins will always be used. The BinOrigin and BinSpacing will be set so that they provide a mapping from bin index to scalar value.

virtual void vtkImageHistogram::AutomaticBinningOn ( )

virtual

If this is On, then the histogram binning will be done automatically. For char and unsigned char data, there will be 256 bins with unit spacing. For data of type short and larger, there will be between 256 and MaximumNumberOfBins, depending on the range of the data, and the BinOrigin will be set to zero if no negative values are present, or to the smallest negative value if negative values are present. For float data, the MaximumNumberOfBins will always be used. The BinOrigin and BinSpacing will be set so that they provide a mapping from bin index to scalar value.

virtual void vtkImageHistogram::AutomaticBinningOff ( )

virtual

If this is On, then the histogram binning will be done automatically. For char and unsigned char data, there will be 256 bins with unit spacing. For data of type short and larger, there will be between 256 and MaximumNumberOfBins, depending on the range of the data, and the BinOrigin will be set to zero if no negative values are present, or to the smallest negative value if negative values are present. For float data, the MaximumNumberOfBins will always be used. The BinOrigin and BinSpacing will be set so that they provide a mapping from bin index to scalar value.

virtual int vtkImageHistogram::GetAutomaticBinning ( )

virtual

If this is On, then the histogram binning will be done automatically. For char and unsigned char data, there will be 256 bins with unit spacing. For data of type short and larger, there will be between 256 and MaximumNumberOfBins, depending on the range of the data, and the BinOrigin will be set to zero if no negative values are present, or to the smallest negative value if negative values are present. For float data, the MaximumNumberOfBins will always be used. The BinOrigin and BinSpacing will be set so that they provide a mapping from bin index to scalar value.

virtual void vtkImageHistogram::SetMaximumNumberOfBins ( int )

virtual

The maximum number of bins to use when AutomaticBinning is On. When AutomaticBinning is On, the size of the output histogram will be set to the full range of the input data values, unless the full range is greater than this value. By default, the max value is 65536, which is large enough to capture the full range of 16-bit integers.

virtual int vtkImageHistogram::GetMaximumNumberOfBins ( )

virtual

The maximum number of bins to use when AutomaticBinning is On. When AutomaticBinning is On, the size of the output histogram will be set to the full range of the input data values, unless the full range is greater than this value. By default, the max value is 65536, which is large enough to capture the full range of 16-bit integers.

virtual void vtkImageHistogram::SetNumberOfBins ( int )

virtual

virtual int vtkImageHistogram::GetNumberOfBins ( )

virtual

The number of bins in histogram (default 256). This is automatically computed unless AutomaticBinning is Off.

virtual void vtkImageHistogram::SetBinOrigin ( double )

virtual

The value for the center of the first bin (default 0). This is automatically computed unless AutomaticBinning is Off.

virtual double vtkImageHistogram::GetBinOrigin ( )

virtual

The value for the center of the first bin (default 0). This is automatically computed unless AutomaticBinning is Off.

virtual void vtkImageHistogram::SetBinSpacing ( double )

virtual

The bin spacing (default 1). This is automatically computed unless AutomaticBinning is Off.

Use a stencil to compute the histogram for just a part of the image.

vtkImageStencilData* vtkImageHistogram::GetStencil ( )

Use a stencil to compute the histogram for just a part of the image.

void vtkImageHistogram::SetStencilConnection ( vtkAlgorithmOutput * algOutput )

Equivalent to SetInputConnection(1, algOutput).

virtual void vtkImageHistogram::SetGenerateHistogramImage ( int )

virtual

If this is On, then a histogram image will be produced as the output. Regardless of this setting, the histogram is always available as a vtkIdTypeArray from the GetHistogram method.
