Detailed Description

compute the outliers in a set of 2D histograms and extract the corresponding row data.

This class takes a table and one or more vtkImageData histograms as input and computes the outliers in that data. In general it does so by identifying histogram bins that are removed by a median (salt and pepper) filter and below a threshold. This threshold is automatically identified to retrieve a number of outliers close to a user-determined value. This value is set by calling SetPreferredNumberOfOutliers(int).

The image data input can come either as a multiple vtkImageData via the repeatable INPUT_HISTOGRAM_IMAGE_DATA port, or as a single vtkMultiBlockDataSet containing vtkImageData objects as blocks. One or the other must be set, not both (or neither).

The output can be retrieved as a set of row ids in a vtkSelection or as a vtkTable containing the actual outlier row data.

Member Function Documentation

static vtkComputeHistogram2DOutliers* vtkComputeHistogram2DOutliers::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkSelectionAlgorithm.

virtual const char* vtkComputeHistogram2DOutliers::GetClassName ( ) [virtual]

Reimplemented from vtkSelectionAlgorithm.

Reimplemented in vtkPComputeHistogram2DOutliers.

static int vtkComputeHistogram2DOutliers::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.

virtual int vtkComputeHistogram2DOutliers::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.

void vtkComputeHistogram2DOutliers::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.
