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 … See more Let n be a fixed non-negative integer. Let C denote the set of all real-valued functions defined over the set of real numbers such that each function in the set as well its first n derivatives are continuous everywhere. A bi-infinite sequence . … See more The cardinal B-spline $${\displaystyle N_{m}(x)}$$ of order m generates a multi-resolution analysis. In fact, from the elementary properties of these functions enunciated above, it follows that the function $${\displaystyle N_{m}(x)}$$ is square integrable and … See more The spline wavelets generated using the interpolatory wavelets are not compactly supported. Compactly supported B-spline wavelets were … See more Elementary properties 1. The support of $${\displaystyle N_{m}(x)}$$ is the closed interval $${\displaystyle [0,m]}$$. 2.
