Enum EndEffectStrategy 

#[non_exhaustive]
pub enum EndEffectStrategy {
    LinearSlope,
    MirrorExtrema {
        num_extrema: usize,
    },
    SymmetricExtension {
        num_extrema: usize,
    },
    AutoRegressive {
        order: usize,
        extension_length: usize,
    },
}

Strategy used to mitigate envelope end effects during EMD sifting.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LinearSlope

Linearly extrapolate each boundary from the two nearest extrema.

MirrorExtrema

Position-reflect the num_extrema nearest extrema around each boundary (x → −x on the left, x → 2(n−1) − x on the right) and add them to the spline knot set with their original y values. Rilling, Flandrin & Gonçalves (2003) §III.

Fields

num_extrema: usize

SymmetricExtension

Like Self::MirrorExtrema but with value-symmetric y values: y = 2·data[boundary] − data[extremum]. Zeng & He (2004).

Fields

num_extrema: usize

AutoRegressive

Fit an AR(p) model and extend the signal extension_length samples on each side before extrema detection. Dätig & Schlurmann (2004).

Fields

order: usize

extension_length: usize

Trait Implementations

impl Clone for EndEffectStrategy

fn clone(&self) -> EndEffectStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EndEffectStrategy

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

Formats the value using the given formatter.

impl PartialEq for EndEffectStrategy

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