Detailed Description

template<class Classifier>
struct BoostClassifier< Classifier >

A classifier that classifies using a majority vote of N (weak) classifier. Classifier could be any kind of weak classifier (Discrete or Real) Result are voted for majority

Member Function Documentation

template<class T >

void BoostClassifier< T >::load

(

std::istream &

in

)

load weak classifier from a stream

template<class Classifier>

float BoostClassifier< Classifier >::max_response ( ) const

inline

return the sum alphas associated to weak classifiers

Deprecated:

template<class Classifier>

template<class DataType >

float BoostClassifier< Classifier >::operator() ( const DataType  data ) const

inline

The classifier operator. Runs the weak classifier and returns the sum of responses

Returns

the sum of single classifiers multiplied by their weights

template<class Classifier>

template<class DataType , class Param1 >

float BoostClassifier< Classifier >::operator() ( const DataType  data, Param1  p1  ) const

inline
