The Construction of Two-Dimensional Four-direction Multi-wavelet
Aliya Yusha · Journal of Sichuan Normal University · 2015
In this paper,the notions of two-dimensional four-direction multi-scaling function and the notion of two-dimensional four-direction multi-wavelet are introduced. The two-dimensional four-direction refinable equation is studied. The construction algorithm of two-dimensional four-direction multi-scaling function is offered. The construction algorithm of the corresponding orthogonal twodimensional four-direction multi-wavelet is offered also.
