Histogram comparison methods @ingroup imgproc_hist

Variants

HISTCMP_CORREL

Correlation where and is a total number of histogram bins.

HISTCMP_CHISQR

Chi-Square

HISTCMP_INTERSECT

Intersection

HISTCMP_BHATTACHARYYA

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

HISTCMP_CHISQR_ALT

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

HISTCMP_KL_DIV

Kullback-Leibler divergence

Trait Implementations

impl Clone for HistCompMethods

fn clone(&self) -> HistCompMethods

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HistCompMethods

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<HistCompMethods> for HistCompMethods

fn eq(&self, other: &HistCompMethods) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
