摘要
引入了对应于双向加细尺度的3带正交双向小波包,建立了紧支撑3带正交双向小波包的理论框架.讨论了这类正交双向小波包的性质.结果表明,正交双向小波包不仅具有传统小波包的特点,同时在应用中具有较强的灵活性.
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 wavelet packets,but also are more flexible in application.
