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. WebNov 8, 2024 · Thus, given the refinable function \(\phi ^{k}\), the first step of the construction of the non-stationary biorthogonal wavelets is to obtain the dual refinable function \(\tilde{\phi }^{k}\)..
