In this paper,we present a new method and visualization technology for exploring subtle traps using narrow band wavelet scanning.

本文提出了一种利用窄带子波扫描探测隐蔽圈闭的方法及可视化处理技术。

Similar to the notations from the extention of 2-band wavelets to 2-band wavelet packets, the theory framework of M-band wavelet packets is developed, a generalization of the notat.

本文用类似于从2带正交子波基扩展到2带子波包的概念,建立了M带子波包的的理论框架,并把有关2带子波包的定义、概念和性质推广到一般的M带子波包,给出了相应的证明。

The ability of 2-band wavelet packets to decompose high frequency channels can be employed to improve the properpty of wavelet for time-frequency localization, which makes more kinds of signals for analyzing by wavelet.

2带子波包具有划分较高频率倍频程的能力,可用于改善子波对时间-频率局部化的性能,推广了信号的适用范围。
