Parasitic Discrete Wavelet Transform and its Application on Abnormal Detection
Zhong Zhang, Hiroki Ikeuchi, Tetsuo Miyake, Takashi Imamura · 2007
In this study, in order to improve effectiveness of the abnormal signal detection, first the technique of constituting an average real signal mother wavelet (A-RMW) from two or more real signals was proposed. Then a novel parasitic discrete wavelet transform by using the RMW designed is proposed and it effectiveness has been conformed in the identification of the rattle noise that steering operation mechanism causes.
