BIORTHOGONAL BASES COMPACTLY SUPPORTED WAVELETS PDF

compactly supported dual functions of bivariate box splines of increasing smoothness is provided. Key-Words: multivariate biorthogonal wavelets, multivariate wavelets, box splines, ma- the dual basis which is an a ne set is not gener-. compactly supported orthonormal symmetric dyadic re nable function, except the trivial wavelets. The key step to construct the biorthogonal wavelets is to construct a 2 L2(IR), whose shifts form a Riesz basis or an orthonormal basis of the. bases of wavelets with compact support, and arbitrarily high preassigned .. ” biorthogonal bases,” i.e., to two dual unconditional bases {{ljk; j, k 7/} and {Illjk; j, k .
