| Abstract: | The discrete wavelet transform (DWT) is used to analyse the spectra of pollution clouds in complicated environment and extract the small features.The DWT is a time frequency analysis technology,which detects the subtle small changes in the target spectrum.The results show that the DWT is a quite effective method to extract features of target cloud and improve the reliability of monitoring alarm system. |
