#include <itkSparseImage.h>

Detailed Description

template<typename TNode, unsigned int VImageDimension = 2>
class itk::SparseImage< TNode, VImageDimension >

A storage type for sparse image data.

This class is derived from the Image class. It uses the base class image data for storing pointers to variables of type TNode. The node type must have a member variable m_Index. The node data is stored using the SparseFieldLayer and ObjectStore classes to allow sequential list access to the nodes. This functionality is used in filter classes that process the SparseImage class such as FiniteDifferenceSparseImageFilter. The node type must also have members NodeType* Next and NodeType* Previous. A minimal node class which could be used to create the sparse equivalent of an itk::Image<unsigned char, 2> is shown below:
struct NodeType
{
NodeType* Next;
NodeType* Previous;
unsigned char m_Data;
};
using SparseImageType = itk::SparseImage<NodeType, 2>;
This class provides the method AddNode which allocates a node variable, associates it with the image pixel index (sets m_Index in the node variable) and returns the pointer to the node variable. It is suggested that the user call the FillBuffer method to initialize the image to null pointers before any calls to AddNode. This would allow the user later to distinguish between valid and non-valid pixels.
