基于小波变换的粗大误差去除算法

Method for eliminating the measured bulky errors based on wavelet transformation

将粗大误差作为突变信号,利用小波变换可以准确地对误差点进行定位,给出了利用小波变换去除粗大误差数据点算法,并对小波基的选取进行了讨论。

Let the measured bulky error be treated as sudden changing signal, utilizing wavelet transformation could conduct an accurate location on the error point By the use of wavelet transformation an algorithm for eliminating data point with measured bulky error was presented, and a discussion was carried out on the selection of wavelet base.
