In the mathematical theory of wavelets, a spline wavelet is a wavelet constructed using a spline function. There are different types of spline wavelets. The interpolatory spline wavelets introduced by C.K. Chui and J.Z. Wang are based on a certain spline interpolation formula. Though these wavelets are orthogonal, they do not have compact supports. There is a certain class of wavelets, unique in some sense, constructed using B-splines and having compact supports. Even though t… WebApr 8, 2024 · The spline wavelets may be classified in four different categories: orthogonal (Battle–Lemarie), semi-orthogonal (e.g., B-spline), shift-orthogonal, and biorthogonal. Splines have precise formulae in the time and frequency domain, which substantially simplifies their manipulation, unlike the majority of other wavelet bases. easiest giraffe in a treadmill
