Struct Gray 

pub struct Gray { /* private fields */ }

A single-channel 8-bit image: row-major samples carried with their dimensions.

Implementations

impl Gray

pub fn shifted(&self, shift: Shift) -> Gray

Moves the image by shift, leaving zeros behind it. OpenCV’s shiftMat, except that a shift larger than the image is allowed and empties it.

impl Gray

pub fn from_vec(data: Vec<u8>, width: usize, height: usize) -> Self

Panics unless data.len() == width * height.

pub fn from_rgb(rgb: &[u8], width: usize, height: usize) -> Self

Interleaved 8-bit RGB flattened with the paper’s weights, which sum to exactly 256. Ward notes the green channel alone works as well.

Panics unless rgb.len() == width * height * 3.

pub fn width(&self) -> usize

pub fn height(&self) -> usize

pub fn as_slice(&self) -> &[u8]

pub fn sample(&self, x: usize, y: usize) -> u8

Trait Implementations

impl Clone for Gray

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
