Base class for all data objects in ITK.
SmartPointer< Self > Pointer
Base class for filters that take an image as input and overwrite that image as the output.
Control indentation during Print() invocation.
Definition: itkIndent.h:50
Light weight base class for most itk classes.
DataObject * GetOutput(const DataObjectIdentifierType &key)
DataObjectPointerArray::size_type DataObjectPointerArraySizeType
Decorates any "simple" data type (data types without smart pointers) with a DataObject API.
Enum classes for HashImageFilter.
Generates a md5 hash string from an image.
