Fields

Name	Description
Bhattacharyya	Bhattacharyya distance [CV_COMP_BHATTACHARYYA]
Chisqr	Chi-Square [CV_COMP_CHISQR]
ChisqrAlt	Alternative Chi-Square \f[d(H_1,H_2) = 2 * \sum _I \frac{\left(H_1(I)-H_2(I)\right)^2}{H_1(I)+H_2(I)}\f] This alternative formula is regularly used for texture comparison. See e.g. @cite Puzicha1997
