New Stable Biorthogonal Spline-Wavelets on the Interval

WebOct 1, 2001 · Cubic spline basis functions have a simple explicit analytic form, and are easy to manipulate. B-spline wavelet converges to a modulated Gaussian as the order of the spline goes to infinity. In this paper, the biorthogonal cubic spline and B-spline wavelets built by a lifting scheme [5], [6] are considered for areal surface characterisation ... 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. the prints and the potter worcester ma
