Member Function Documentation

double IntegralHistogram::CalcSimilarity	(	ColorHistogram< unsigned char > &	chist,
		int	ux,
		int	uy,
		int	lx,
		int	ly
	)

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

Parameters

chist	= the colorHistogram we compare with
roi	= the roi to compare with: upperx, uppery, lowerx, lowery

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

double IntegralHistogram::CalcSimilarity	(	ColorHistogram< unsigned char > &	chist1,
		int	ux1,
		int	uy1,
		int	lx1,
		int	ly1,
		ColorHistogram< unsigned char > &	chist2,
		int	ux2,
		int	uy2,
		int	lx2,
		int	ly2,
		double	weightSecond = `0.5`
	)

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

The similarity is calculated for two image regions/histograms the resulting probability is the weighted sum of both.

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