4.7 Wavelet Families
In a practical way, wavelet decomposition is done using wavelet lters.
Varieties of wavelet lters are available, which are grouped under different
families (e.g., Haar, Daubechies, Coeiet, Morlet, Mayer, etc.). These wavelet
lters are based on the wavelet function, which satises all criteria.
The type of lter, its length, and the number of decomposition stages
should be considered when the wavelet transform is used for decomposition.
All the wavelets are theoretically reversible, but due to oating point arith-
metic used in any processor and precision limitation, wavelet transform a ...
