Detailed Description

template<class TLabel = unsigned short, class TMass = double>
class otb::MassOfBelief< TLabel, TMass >

This class represent a mass of belief function.

This class represent a Mass of Belief function to be used in Dempster-Shafer theory.

Template parameter TLabel is the type of the elements in the universe set, while TMass is the type of the mass. TLabel can be any type implementing ordering operator, while TMass should be a floating point type.

An element of the power-set is represented by the sub-type LabelSetType, which is a std::set<TLabel>.

A mass can be associated with a given element from the power set by calling the SetMass method. It is not necessary to associate masses with each element of the power set: mass is supposed to be null otherwise declared.

A mass associated with an element from the power-set can be removed using the RemoveMass method, and all masses can be cleared using the Clear() function.

The mass associated with a given element from the power-set can be retrieved using the GetMass method. If no mass has been associated with this element, null is returned.

The Normalize() method allows normalizing all masses so that they sum to 1. The EstimateUncertainty() method allows associating to the uncertain set (i.e. the universe set) a mass so that all masses sum to 1.

The GetUniverse() method allows retrieving the set of all symbols (i.e. the universal set), while the GetSupport() method allows retrieving the set of all elements of the power-set for which a mass has been associated. This method returns a LabelSetOfSetType, which is a std::set<std::set<TLabel> >.

The mass function can be optionally initialized from a given universe set by building the power-set and associating a null mass with every elements of this power-set. This allows ensuring that two mass functions will share the exact same universe and power-set, but is not mandatory, since mass is supposed to be null for any set if not stated otherwise.

Once masses are set, the GetPlausibility() and GetBelief() function allow computing the belief and plausibility for an element of the power-set, or directly for a set of elements of the power-set intersecting (resp. contained in) a given hypothesis.
