Construction of a type of Biorthogonal Binary Wave Functions by Multiresolution Analysis Approach
Delin Hua · Physics Procedia · 2012
Abstract Wavelet analysis is nowadays a widely used tool in applied mathematics. The concept of vector-valued binary wavelets with two-scale dilation factor associated with an orthogonal vector-valued scaling function is introduced. The existence of orthogonal vector-valued wavelets with two-scale is discussed. A necessary and sufficient condition is provided by means of vector-valued multiresolution analysis and paraunitary vector filter bank theory. An algorithm for constructing a sort of orthogonal vector-valued wavelets with compact support is proposed, and their orthogonal properties are investigated.
