Struct IntegralImage 

pub struct IntegralImage { /* private fields */ }

Summed-area table with a zero top row and left column.

Implementations

impl IntegralImage

pub const fn source_width(&self) -> usize

Source image width, excluding the zero border.

pub const fn source_height(&self) -> usize

Source image height, excluding the zero border.

pub const fn width(&self) -> usize

Integral table width (source_width + 1).

pub const fn height(&self) -> usize

Integral table height (source_height + 1).

pub fn as_slice(&self) -> &[f64]

Row-major integral values.

pub fn sum_region( &self, x0: usize, y0: usize, x1: usize, y1: usize, ) -> Result<f64, VisionError>

Returns the sum over half-open source rectangle [x0,x1) × [y0,y1).

Trait Implementations

impl Clone for IntegralImage

fn clone(&self) -> IntegralImage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntegralImage

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

Formats the value using the given formatter.

impl PartialEq for IntegralImage

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

Tests for self and other values to be equal, and is used by ==.

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

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