Detailed Description

template<class Aggregator>
struct DataSetHandle< Aggregator >

A collection of "Patterns", preprocessed data.

Pattern contains all data usefull for train (algorithm dependent data). A dataset that collect pattern but not remove them in the destroyer automatically

Note

only for binary classifier, for multiclass problem

Il DataSet deve contenere un vettore di Dati+DatiExtraAlgoritmo oltre ai Parametri per poter estrarre le feature dai Dati. Permette la conversione tra DataSetHandle, copiando solo il descrittore.

TPatternType the type of pattern. Must have at least category member. TParamType parameters of DataType (inside Pattern) to declare the data (for example width,height). Parameters common to all the DataType

Constructor & Destructor Documentation

template<class Aggregator>

template<class SrcAggregator >

DataSetHandle< Aggregator >::DataSetHandle ( const DataSetHandle< SrcAggregator > &  src )

inlineexplicit

DataSet conversion costructor. Used to convert a Patern type to an extended Pattern type (for example AdaBoostPattern)

Member Function Documentation

template<class Aggregator >

void DataSetHandle< Aggregator >::Import	(	const DataType &	data,
		int	category
	)

Import data inside the set

Note

buf will be freed inside this library at release

template<class Aggregator>

template<class SrcAggregator >

void DataSetHandle< Aggregator >::operator= ( const DataSetHandle< SrcAggregator > &  src )

inline

copy operator (copy and convert)

Note

do not release old memory since it is inside the DataSetHandle

template<class Aggregator>

void DataSetHandle< Aggregator >::SetParams ( const ParamType &  src )

inline

Set the geometry of patterns. All pattern must have the same geometry.

Member Data Documentation

template<class Aggregator>

unsigned int DataSetHandle< Aggregator >::n_patternP

Number of patterns in two dataset (P: Positive, N: Negative)
