orthogonal wavelets

thumb|right|Coiflet with two vanishing moments Coiflets are discrete wavelets designed by Ingrid Daubechies, at the request of Ronald Coifman, to have scaling functions with vanishing moments. The wavelet is near symmetric, their wavelet functions have N/3 vanishing moments and scaling functions N/3-1, and has been used in many applications using Calderón–Zygmund operators.
