Struct GaussianKernel 

pub struct GaussianKernel { /* private fields */ }

Reusable fixed-point Gaussian blur kernel.

Implementations

impl GaussianKernel

pub fn new(radius: u32, sigma: f32) -> Self

Precompute weights for a Gaussian blur radius and sigma.

pub fn from_weights( radius: u32, weights: Vec<u32>, ) -> Result<Self, GaussianKernelError>

Build a kernel from caller-owned precomputed fixed-point weights.

Errors

Returns an actionable error when weights.len() does not match 2 * min(radius, MAX_RADIUS) + 1.

pub const fn radius(&self) -> u32

Clamped kernel radius.

pub fn weights(&self) -> &[u32]

Fixed-point 16.16 weights.
