InPlaceLabelMapFilter< TImage > Superclass
Light weight base class for most itk classes.
LabelObjectType::AttributeType AttributeType
virtual void AllocateOutputs() override
Remove objects according to the value of their shape attribute.
Base class for filters that takes an image as input and overwrites that image as the output...
Implements progress tracking for a filter.
void TemplatedGenerateData(const TAttributeAccessor &accessor)
OutputImageType * GetOutput()
Control indentation during Print() invocation.
Definition: itkIndent.h:49
void PrintSelf(std::ostream &os, Indent indent) const override
DataObjectPointerArraySizeType GetNumberOfIndexedOutputs() const
The number of defined Indexed outputs.
