Detailed Description

template<class StorageType>
class BIAS::ColorMultiHistogram< StorageType >

This Class handels MultiHistogram matters on Images.

it is derived from Colorhistogram, to make it usable just like a normal ColorHistogram It represents a Multihistogram and offers the same Methods as ColorHistogram

Author: Ingo Schiller March 2004 MultiHistogram is represented by two ColorHistograms untested

template<class StorageType >

double BIAS::ColorMultiHistogram< StorageType >::CalcSimilarity ( const ColorMultiHistogram< StorageType > & chist ) const

Calculates the Bhattacharyya similarity Coeiffient^2 which is the distance or difference of 2 ColorMultiHistograms.

simply call the CalcSimilarity from ColorHistograms here and multiply the values.

Parameters

the	hist to compare with

Returns: double value, which indicates the similarity. 1 if similar.

Author: schiller March 2004

This is the distance of the MultiHistogram

template<class StorageType >

double BIAS::ColorMultiHistogram< StorageType >::CalcSimilarityColorWeighted ( const BIAS::ColorMultiHistogram< StorageType > & chist ) const

Calculates the Bhattacharyya similarity Coeiffient^2 which is the distance or difference of 2 ColorMultiHistograms.

Same As CalcSimilarity, but the two histogram values are weighted according to the amount of color bins which are not zero.

Parameters

the	hist to compare with

Returns: double value, which indicates the similarity. 1 if similar.

template<class StorageType >

void BIAS::ColorMultiHistogram< StorageType >::Dump	(	std::ostream &	os = `std::cout`,
		std::ostream &	os2 = `std::cout`
	)

dumps information on the MultiHistogram calls the Dump of ColorHistogram

dumps information on MultiHistogram to ostreams format: first hist1, then hist2 binsize tab ux tab uy tab lx tab ly hs histogram, as a matrix with binsize x binsize (tab separated) l values as a line with lenght binsize (tab separated)

Parameters

os	= the outstream, default std::cout

Parameters

image = the image

Returns: -1 if image does not exist
