Detailed Description

The description scheme defines the set of attributes (Attribute) to be used for feature extraction systems.

A DescriptionScheme is only an specification. The real data is held in a DescriptionDataPool, a container that fits its structure to the one defined on the DescriptionScheme specification.

Attributes in a DescriptionScheme have a name and a type and they are organized in scopes. Each scope (see DescriptionScope) defines a kind of target for the attributes: (note scope, sample scope, frame scope, phrase scope, sample scope...)

You can add Attributes to the DescriptionScheme by using the DescriptionScheme::AddAttribute method. The rest of the methods are utility for the pool classes.

Member Function Documentation

template<typename DataType >

void CLAM::DescriptionScheme::AddAttribute	(	const std::string &	scope,
		const std::string &	name
	)			[inline]

Adds a new attribute to the description scheme.

If the scope does not exist it will be added.

Precondition:

The name is alphanumeric

The scope has no other attribute with the same name

Parameters:

	DataType	The type of the argument to be added
	scope	The scope where the attributes applies to
	name	The name for the attribute
