Struct WaveletTransform 

pub struct WaveletTransform {
    pub family: WaveletFamily,
}

1-D Discrete Wavelet Transform with pluggable filter bank.

Supports Haar, Daubechies-4, and Symlet-4 wavelets for single-level and multi-level decomposition/reconstruction.

Fields

family: WaveletFamily

The wavelet family used by this transform.

Implementations

impl WaveletTransform

pub fn new(family: WaveletFamily) -> Self

Create a new WaveletTransform using the given wavelet family.

pub fn forward_one_level(&self, signal: &[f64]) -> (Vec<f64>, Vec<f64>)

Perform one level of the forward DWT.

Returns (approximation, detail) coefficient vectors.

pub fn inverse_one_level(&self, approx: &[f64], detail: &[f64]) -> Vec<f64>

Perform one level of the inverse DWT (reconstruction).

Returns the reconstructed signal from approximation and detail coefficients.

pub fn energy(coeffs: &[f64]) -> f64

Compute the energy (sum of squared coefficients) of a coefficient slice.

pub fn entropy(coeffs: &[f64]) -> f64

Compute the Shannon entropy of coefficient energies (normalized).

Returns - Σ p_i ln(p_i) where p_i = c_i² / total_energy.
