An approximation of Daubechies wavelet matrices by perfect reconstruction filter banks with rational coefficients
Lasha Ephremidze, Aleksander Gamkrelidze, Edem Lagvilava
It is described how the coefficients of Daubechies wavelet matrices can be approximated by rational numbers in such a way that the perfect reconstruction property of the filter ban…
