Optimal model for 4-band biorthogonal wavelets bases for fast calculation

Wang G, Yuan W. Introduction As a generalization of orthogonal wavelets, the biorthogonal wavelets have become a fundamental tool in many areas of applied mathematics, basez signal processing cojpactly numerical analysis [ 1 — 8 ]. We can use an extra degree of freedom to minimize the maximum eigenvalue. Footnotes Competing interests The authors declare that they have no competing interests. Bi orthogonal real-valued multi-band wavelets with symmetry have been reported in [ 10 — 121617 ].
