Characteristics of orthogonal two-direction wavelet packets. (Chinese. English summary) Zbl 1240.42170
Summary: The concept of orthogonal two-direction wavelet packets with dilation 3 is given. The theoretical framework of orthogonal two-direction wavelet packets is developed. The properties of two-direction wavelet packets are discussed. It is shown that orthogonal two-direction wavelet packets not only have the characteristic of wavelet packets, but also are more flexible in application.
