represents a Cohen–Daubechies–Feauveau wavelet of type "9/7".
represents a Cohen–Daubechies–Feauveau wavelet of type "type".
- CDFWavelet defines a set of biorthogonal wavelets.
- The following "type" forms can be used:
"5/3" used in lossless JPEG2000 compression "9/7" used in lossy JPEG2000 compression
- The scaling function () and wavelet function () have compact support. The functions are symmetric.
- CDFWavelet can be used with such functions as DiscreteWaveletTransform, WaveletPhi, etc.
