Struct Biorthogonal
pub struct Biorthogonal { /* private fields */ }Expand description
Biorthogonal wavelet family
Biorthogonal wavelets use different filters for decomposition and reconstruction, allowing for symmetric filters (linear phase) while maintaining perfect reconstruction. This is particularly useful in image processing applications.
§Supported Wavelets:
- CDF 5/3 (Cohen-Daubechies-Feauveau): Used in lossless JPEG2000
- CDF 9/7: Used in lossy JPEG2000
- Bior 1.3: Biorthogonal with 3 decomposition and 1 reconstruction vanishing moments
- Bior 1.5: Biorthogonal with 5 decomposition and 1 reconstruction vanishing moments
- Bior 2.2: Biorthogonal with 2 decomposition and 2 reconstruction vanishing moments
- Bior 2.4: Biorthogonal with 4 decomposition and 2 reconstruction vanishing moments
- Bior 2.6: Biorthogonal with 6 decomposition and 2 reconstruction vanishing moments
- Bior 2.8: Biorthogonal with 8 decomposition and 2 reconstruction vanishing moments
- Bior 3.1: Biorthogonal with 1 decomposition and 3 reconstruction vanishing moments
- Bior 3.3: Biorthogonal with 3 decomposition and 3 reconstruction vanishing moments
- Bior 3.5: Biorthogonal with 5 decomposition and 3 reconstruction vanishing moments
- Bior 3.7: Biorthogonal with 7 decomposition and 3 reconstruction vanishing moments
- Bior 3.9: Biorthogonal with 9 decomposition and 3 reconstruction vanishing moments
- Bior 4.4: Biorthogonal with 4 decomposition and 4 reconstruction vanishing moments
- Bior 5.5: Biorthogonal with 5 decomposition and 5 reconstruction vanishing moments
- Bior 6.8: Biorthogonal with 8 decomposition and 6 reconstruction vanishing moments
