pub struct Cdf53Transform { /* private fields */ }

CDF 5/3 Integer Wavelet Transform

Implementations

impl Cdf53Transform

pub fn new(levels: usize) -> Self

Create a new CDF 5/3 transform with specified levels

pub fn forward( &self, image: &[i32], width: usize, height: usize, ) -> Result<Vec<i32>>

Forward transform: image → wavelet coefficients (dense)

pub fn inverse( &self, coefficients: &[i32], width: usize, height: usize, ) -> Result<Vec<i32>>

Inverse transform: wavelet coefficients (dense) → image

pub fn quantize( &self, buffer: &mut [i32], width: usize, height: usize, table: &QuantizationTable, )

Quantize coefficients using 360-prime pattern (in-place)
