摘要
本文基于小波多分辨率的特性,根据其去噪原理,将其应用到数字化数据粗差的探测及剔除的处理上,并针对小波阈值方法去除粗差提出了调节阈值的自适应性方法进行了试验分析,达到了预期的目的。
Based on the wavelet multi-resolution characteristics, in accordance with its principle of de-noising, the papers applies it in digital data gross error detection and removing, and analysis methods for test about removing gross error of adjusting the threshold value of the adaptive against wavelet threshold value, which indicates the method presented in this paper is effective.
