Biorthogonal spline wavelets
WebSearch ACM Digital Library. Search Search. Advanced Search WebNew algorithms for fast wavelet transforms with biorthogonal spline wavelets on nonuniform grids are presented. In contrast to classical wavelet transforms, the algorithms are not based on filter coefficients, but on algorithms for B-spline expansions (differentiation, Oslo algorithm, etc.). Due to inherent properties of the spline wavelets, …

WebJan 14, 2010 · In this paper we present the construction of new stable biorthogonal spline-wavelet bases on the interval [0, 1] for arbitrary choice of spline-degree. As starting point, we choose the well-known family of compactly supported biorthogonal spline-wavelets presented by Cohen, Daubechies and Feauveau. Firstly, we construct biorthogonal … 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 …
