Constructor & Destructor Documentation

◆ AdaptiveThresholdIterator() [1/3]

template<class TImage , class TFunction >
itk::AdaptiveThresholdIterator< TImage, TFunction >::AdaptiveThresholdIterator ( ImageType *  imagePtr,
FunctionType *  fnPtr,
IndexType  startIndex 
)

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor uses an explicit seed pixel for the flood fill, the "startIndex"

◆ AdaptiveThresholdIterator() [2/3]

template<class TImage , class TFunction >
itk::AdaptiveThresholdIterator< TImage, TFunction >::AdaptiveThresholdIterator ( ImageType *  imagePtr,
FunctionType *  fnPtr,
std::vector< IndexType > &  startIndex 
)

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor uses an explicit list of seed pixels for the flood fill, the "startIndex"

◆ AdaptiveThresholdIterator() [3/3]

template<class TImage , class TFunction >
itk::AdaptiveThresholdIterator< TImage, TFunction >::AdaptiveThresholdIterator ( ImageType *  imagePtr,
FunctionType *  fnPtr 
)

Constructor establishes an iterator to walk a particular image and a particular region of that image. This version of the constructor should be used when the seed pixel is unknown

◆ ~AdaptiveThresholdIterator()

template<class TImage , class TFunction >
itk::AdaptiveThresholdIterator< TImage, TFunction >::~AdaptiveThresholdIterator ( )
inlineoverride

Default Destructor.

Definition at line 101 of file itkAdaptiveThresholdIterator.h.

template<class TImage , class TFunction >
virtual SmartPointer<FunctionType> itk::AdaptiveThresholdIterator< TImage, TFunction >::GetFunction ( ) const

◆ GetIndex()

template<class TImage , class TFunction >
const IndexType itk::AdaptiveThresholdIterator< TImage, TFunction >::GetIndex ( )
inlineoverride

Get the index. This provides a read only reference to the index. This causes the index to be calculated from pointer arithmetic and is therefore an expensive operation.

)

Dimension of the image the iterator walks. This constant is needed so that functions that are templated over image iterator type (as opposed to being templated over pixel type and dimension) can have compile time access to the dimension of the image that the iterator walks.
