Orthogonality Relations for Cardinal B-Splines over Bounded Intervals

Part of the Focus on Computer Graphics book series (FOCUS COMPUTER)


Starting from the recently discovered orthogonality relations for cardinal B-splines over the real line we derive suitably modified bilinear forms providing orthonormality over bounded intervals. We conjecture that these bilinear forms are positive definite and therefore inner products for B-splines of arbitrary order n ∈ IN. For n ≤ 8, this is verified by explicit computation of the corresponding matrices. Further, applications to approximation theory are discussed.
