WebIf the filters have an even length and are symmetric with respect to n=1/2, then the scaling functions are symmetric with respect to n=1/2, while the wavelets are antisymmetric. Example. Spline wavelets and scaling … Webrepresentatives of the Cohen-Daubechies-Feauveau class of biorthogonal wavelets 7 are splines as well. This is because the iteration of the binomial refinement filter — which is a crucial component in any wavelet construction — converges to the B-spl ine which is the generating function for polynomial splines. 2.
