Histogram comparison methods @ingroup imgproc_hist

Variants

HISTCMP_CORREL = 0

Correlation where and is a total number of histogram bins.

HISTCMP_CHISQR = 1

Chi-Square

HISTCMP_INTERSECT = 2

Intersection

HISTCMP_BHATTACHARYYA = 3

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

HISTCMP_CHISQR_ALT = 4

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

HISTCMP_KL_DIV = 5

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 From<HistCompMethods> for i32

fn from(v: HistCompMethods) -> Self

Converts to this type from the input type.

impl PartialEq 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for HistCompMethods

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
