Biorthogonal spline wavelets
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. WebJan 1, 2004 · Multivariate biorthogonal spline waveletsMultivariate biorthogonal spline (or general) wavelets can be constructed through tensor products. For ease of exposure, we start from one group of biorthogonal spline wavelets φ,ψ, φ ̃, ψ ̃ and their associated MRA 〈V j 〉 j∈ Z and 〈 V ̃ j 〉 j∈ Z. This is also enough for most applications.
