Daubechies
Ingrid Daubechies, one of the brightest stars in the world of wavelet research, invented what are called compactly supported orthonormal wavelets -- thus making discrete wavelet analysis practicable.
The names of the Daubechies family wavelets are written dbN
, where N
is the order, and db
the "surname" of the wavelet. The db1
wavelet, as mentioned above, is the same as Haar
wavelet. Here are the next nine members of the family:
You can obtain a survey of the main properties of this family by typing waveinfo('db')
from the MATLAB command line. See Daubechies Wavelets: dbN for more detail.
