Multivariate Semi-orthogonal Wavelet Packets
Jian Yang · Gongcheng shuxue xuebao · 2003
An algorithm to construct compactly supported semiorthogonal wavelet packets of L2(Rs) is presented. We have a wide choice of the decomposition coefficients in our construction, furthermore the wavelet packets are generalization of the basic wavelet packets. With these packets. We can choose the various bases of L2(Rs) flexibly.
