struct returned by cv::moments

The spatial moments are computed as:

The central moments are computed as:

where is the mass center:

The normalized central moments are computed as:

Note: , , hence the values are not stored.

The moments of a contour are defined in the same way but computed using the Green’s formula (see http://en.wikipedia.org/wiki/Green_theorem). So, due to a limited raster resolution, the moments computed for a contour are slightly different from the moments computed for the same rasterized contour.

Note: Since the contour moments are computed using Green formula, you may get seemingly odd results for contours with self-intersections, e.g. a zero area (m00) for butterfly-shaped contours.

Implementations

impl Moments

pub fn default() -> Result<Moments>

the default constructor

pub fn new( m00: f64, m10: f64, m01: f64, m20: f64, m11: f64, m02: f64, m30: f64, m21: f64, m12: f64, m03: f64 ) -> Result<Moments>

the full constructor

Trait Implementations

impl Clone for Moments

fn clone(&self) -> Moments

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Moments

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

Formats the value using the given formatter.

impl PartialEq for Moments

fn eq(&self, other: &Moments) -> 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.
