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 ...
WebApr 1, 1998 · In this paper we detail the general construction principle of the WEM to the 1D, 2D and 3D cases. We address additional features such as symmetry, vanishing moments and minimal support of the wavelet functions in each particular dimension. The construction is illustrated by using biorthogonal spline wavelets on the interval.
