Expand description

The distance metric choices for histogram comparisons

Variants§

§

Correlation

$d(H_1,H_2) = \frac{\sum_I (H_1(I) - \bar{H_1}) (H_2(I) - \bar{H_2})}{\sqrt{\sum_I(H_1(I) - \bar{H_1})^2 \sum_I(H_2(I) - \bar{H_2})^2}}$

§

ChiSquare

$d(H_1,H_2) = \sum _I \frac{\left(H_1(I)-H_2(I)\right)^2}{H_1(I)}$ First histogram may not have empty bins

§

Intersection

$d(H_1,H_2) = \sum _I \min (H_1(I), H_2(I))$

§

Hellinger

$d(H_1,H_2) = \sqrt{1 - \frac{1}{\sqrt{\int{H_1} \int{H_2}}} \sum_I \sqrt{H_1(I) \cdot H_2(I)}}$ Both histograms need to be normalizable
