Biorthogonal spline wavelets
WebOrthogonal and biorthogonal wavelets are designated as type 1 and type 2 wavelets respectively in the wavelet manager, wavemngr. Valid built-in orthogonal wavelet families are ... Biorthogonal Spline ("bior"), and … WebAnalytic wavelets, derived from the complexification of HT wavelet pairs, exhibit a one-sided spectrum. Based on the tensor-product of such analytic wavelets, and, in effect, by appropriately combining four separable biorthogonal wavelet bases of L2(R2), we then discuss a methodology for constructing 2-D directional-selective complex wavelets.

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.
