Spectral Wavelet Transform

Implementations

impl SpectralWaveletTransform

pub fn new(laplacian: ScaledLaplacian, num_scales: usize, degree: usize) -> Self

Create wavelet transform with logarithmically spaced scales

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

Forward transform: compute wavelet coefficients Returns (scaling_coeffs, [wavelet_coeffs_scale_0, wavelet_coeffs_scale_1, …])

pub fn inverse( &self, scaling_coeffs: &[f64], wavelet_coeffs: &[Vec<f64>], ) -> Vec<f64>

Inverse transform: reconstruct signal from coefficients Note: Perfect reconstruction requires frame bounds analysis

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

Compute wavelet energy at each scale

pub fn wavelets_at(&self, vertex: usize) -> Vec<GraphWavelet>

Get all wavelets centered at a vertex

pub fn num_scales(&self) -> usize

Number of scales

pub fn scale_values(&self) -> Vec<f64>

Get scale parameters
