Constructor & Destructor Documentation

gtsam::MFAS::MFAS ( const std::map< KeyPair, double > &  edgeWeights )

inline

Construct from the weighted directed edges between the nodes. Each node is identified by a Key.

Parameters

edgeWeights

weights of edges in the graph

Definition at line 69 of file MFAS.h.

MFAS::MFAS	(	const TranslationEdges &	relativeTranslations,
		const Unit3 &	projectionDirection
	)

Constructor to be used in the context of translation averaging. Here, the nodes of the graph are cameras in 3D and the edges have a unit translation direction between them. The weights of the edges is computed by projecting them along a projection direction.

Parameters

relativeTranslations	translation directions between the cameras
projectionDirection	direction in which edges are to be projected

Member Function Documentation

KeyVector MFAS::computeOrdering

(

)

const

Computes the 1D MFAS ordering of nodes in the graph.

Returns

orderedNodes: vector of nodes in the obtained order

Definition at line 124 of file MFAS.cpp.

map< MFAS::KeyPair, double > MFAS::computeOutlierWeights

(

)

const

Computes the outlier weights of the graph. We define the outlier weight of a edge to be zero if the edge is an inlier and the magnitude of its edgeWeight if it is an outlier. This function internally calls computeOrdering and uses the obtained ordering to identify outlier edges.

Returns

outlierWeights: map from an edge to its outlier weight.
