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
