Enum DenoiseMethod 

pub enum DenoiseMethod {
    Bilateral,
    Gaussian,
    Median,
    Mean,
    Nlmeans,
    Anisotropic,
}

Which spatial denoise algorithm super::VideoFilter::Denoise runs. Each suits a different kind of noise; strength then blends the result with the source. (Temporal denoisers — hqdn3d / NLM-temporal — need frame history and don’t fit this stateless per-frame filter; a future extension.)

Variants

Bilateral

Edge-preserving bilateral filter (5×5): smooths flat / sensor noise while keeping edges sharp. The general-purpose default.

Gaussian

Gaussian low-pass blur (separable 5×5): smooths everything, so it softens fine detail along with the noise.

Median

Median filter (3×3): best for salt-and-pepper / impulse noise; also edge-preserving.

Mean

Mean (box) blur over a 3×3 window — the cheapest smoother; blurs noise and detail equally.

Nlmeans

Non-local means: averages samples weighted by how similar their surrounding patch is, so repeating texture denoises without blurring. Highest classical quality — and by far the slowest.

Anisotropic

Anisotropic diffusion (Perona–Malik): gradient-gated diffusion — smooths flat regions but stops at edges. Edge-preserving like bilateral, different character.

Trait Implementations

impl Clone for DenoiseMethod

fn clone(&self) -> DenoiseMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DenoiseMethod

impl Debug for DenoiseMethod

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

Formats the value using the given formatter.

impl Default for DenoiseMethod

fn default() -> DenoiseMethod

Returns the “default value” for a type.

impl Display for DenoiseMethod

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

impl Eq for DenoiseMethod

impl PartialEq for DenoiseMethod

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