Member Function Documentation

void DBoW2::BowVector::addIfNotExist	(	WordId	id,
		WordValue	v
	)

Adds a word with a value to the vector only if this does not exist yet

Parameters:

	id	word id to look for
	v	value to give to the word if this does not exist

void DBoW2::BowVector::addWeight	(	WordId	id,
		WordValue	v
	)
