Struct Kernel2d 

pub struct Kernel2d { /* private fields */ }

Finite 2D convolution kernel stored in row-major order.

Implementations

impl Kernel2d

pub fn new( width: usize, height: usize, values: impl Into<Vec<f32>>, ) -> Result<Self>

Creates a kernel with non-zero dimensions and matching finite values.

pub fn width(&self) -> usize

Returns the number of columns in the kernel.

pub fn height(&self) -> usize

Returns the number of rows in the kernel.

pub fn values(&self) -> &[f32]

Borrows row-major kernel values.

pub fn validate(&self) -> Result<()>

Verifies dimensions, value count, and finite values.

pub fn identity_3x3() -> Self

Creates a 3x3 identity kernel with a 1.0 center coefficient.

pub fn sharpen_3x3() -> Self

Creates a standard 3x3 sharpen kernel.

pub fn edge_3x3() -> Self

Creates a standard 3x3 edge-detection kernel.

pub fn blur_3x3() -> Self

Creates an unnormalized 3x3 box blur kernel.

pub fn as_array_3x3(&self) -> Result<[f32; 9]>

Copies a 3x3 kernel into a fixed-size row-major array.

Trait Implementations

impl Clone for Kernel2d

fn clone(&self) -> Kernel2d

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Kernel2d

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

Formats the value using the given formatter.

impl From<[f32; 9]> for Kernel2d

fn from(value: [f32; 9]) -> Self

Converts to this type from the input type.

impl PartialEq for Kernel2d

fn eq(&self, other: &Kernel2d) -> 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.
