Histogram comparison methods @ingroup imgproc_hist

Variants

HISTCMP_CORREL

Correlation block formula where block formula and inline formula is a total number of histogram bins.

HISTCMP_CHISQR

Chi-Square block formula

HISTCMP_INTERSECT

Intersection block formula

HISTCMP_BHATTACHARYYA

Bhattacharyya distance (In fact, OpenCV computes Hellinger distance, which is related to Bhattacharyya coefficient.) block formula

HISTCMP_CHISQR_ALT

Alternative Chi-Square block formula This alternative formula is regularly used for texture comparison. See e.g. Puzicha1997

HISTCMP_KL_DIV

Kullback-Leibler divergence block formula

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
