	constructor with n nodes
	drwnNNGraphImage (const drwnNNGraphImageData &image)
	constructor from image data
	~drwnNNGraphImage ()

void	clearNodes ()
	clear all nodes (including features and labels) and out-going edges
void	clearEdges ()
	clears all out-going edges (matches) for this image
void	initialize (const string &name, unsigned n=0)
	initialize number of nodes (no features or labels)
virtual void	initialize (const drwnNNGraphImageData &image)
	initialize nodes with features and labels from image data
void	transformNodeFeatures (const drwnFeatureTransform &xform)
	arbitrary feature transformation
void	appendNodeFeatures (const drwnNNGraphImageData &image, const cv::Mat &features)
	append node features derived from pixel features
void	appendNodeFeatures (const drwnNNGraphImageData &image, const vector< cv::Mat > &features)
	append a set of node features derived from pixel features
size_t	numBytesOnDisk () const
	number of bytes needed on disk
bool	read (istream &is)
	read from a stream (deserialization)
bool	write (ostream &os) const
	write to a stream (serialization)
drwnNNGraphImage	clone (bool bWithFeatures=true) const
	clone the image (with or without node features)
const drwnNNGraphNode &	operator[] (unsigned segId) const
	returns const reference to the node for superpixel segId
drwnNNGraphNode &	operator[] (unsigned segId)
	returns reference to the node for superpixel segId

Public Attributes
bool	bSourceMatchable
	Include this image during update (initialize, propagate, local, search, and enrichment). If false the outgoing edges from all nodes in this image are fixed.
bool	bTargetMatchable
	Allow other image to match to this one. If false no new edges will be created that end at any node in this image (but existing incoming edges may be removed). During updates this has the effect of putting this image in the same equivalence class as all any other image.
int32_t	eqvClass
	Equivalence class for this image. If negative (which is the default) the image is considered to be in its own equivalence class. Images in the same equivalence class will not be matched when learning the superpixel graph.

Protected Member Functions
virtual void	cacheNodeNeighbourhoods (const drwnNNGraphImageData &image)
	cache the spatial neighbours for each node
virtual void	cacheNodeFeatures (const drwnNNGraphImageData &image)
	cache (standard) node features
virtual void	cacheNodeLabels (const drwnNNGraphImageData &image)
	cache node labels

Protected Attributes
string	_name
	basename for this image
vector< drwnNNGraphNode >	_nodes
	nodes associated with this image
