Detailed Description

Class used to access topologies of certain types and neighbour topologies for use in combinatorial optimization. All topologies get evaluated before they are returned. Keeps track of the history of topolgy access and thus optimization.

Definition at line 40 of file TopologyManager.h.

		boost::shared_ptr< AbstractTopologyEvaluator >	pEvaluator
	)

Constructor.

Member Function Documentation

boost::shared_ptr< SceneModel::Topology > ProbabilisticSceneRecognition::TopologyManager::getFullyMeshedTopology ( )

Get fully meshed topology for the object types in the evidence list.

Returns: fully meshed topology.

Definition at line 113 of file TopologyManager.cpp.

boost::shared_ptr< SceneModel::Topology > ProbabilisticSceneRecognition::TopologyManager::getNextNeighbour ( )

virtual

Get the next neighbour of the current reference topology.

Returns: the next neighbour of the current reference topology.

Definition at line 52 of file TopologyManager.cpp.

boost::shared_ptr< SceneModel::Topology > ProbabilisticSceneRecognition::TopologyManager::getRandomTopology ( )

Get a random topology for the object types in the evidence list.

Returns: a random topology.

Definition at line 142 of file TopologyManager.cpp.

std::vector< boost::shared_ptr< SceneModel::Topology > > ProbabilisticSceneRecognition::TopologyManager::getStarTopologies ( )

Get all the star topologies for the object types in the evidence list.

Returns: star topologies.

Definition at line 125 of file TopologyManager.cpp.

bool ProbabilisticSceneRecognition::TopologyManager::hasNextNeighbour ( )

virtual

Check whether the current reference topology has (unseen) neighbours.

Returns: whether the current reference topology has neighbours.

Definition at line 69 of file TopologyManager.cpp.

void ProbabilisticSceneRecognition::TopologyManager::makeTree ( boost::shared_ptr< SceneModel::Topology > pTopology )

Make a tree with references out of a given topology.

Parameters

pTopology to transform into a tree with references.

Definition at line 154 of file TopologyManager.cpp.

void ProbabilisticSceneRecognition::TopologyManager::printHistory ( unsigned int pRunNumber )

Print history of topology access since construction or last call of resetTopologies().

Parameters

pRunNumber Unique ID of current run.

Definition at line 183 of file TopologyManager.cpp.

void ProbabilisticSceneRecognition::TopologyManager::resetTopologies ( )

Forget which topologies have already been used in optimization before running another round. Keeps cached topologies so thex don't have to be rebuilt and reevaluated.

Definition at line 175 of file TopologyManager.cpp.

void ProbabilisticSceneRecognition::TopologyManager::setReferenceInstance ( boost::shared_ptr< SceneModel::Topology > instance )

virtual

Set a new reference topology to get the neighbours for.

Parameters

instance the new reference topology.
