Application of De-Noising Method for Wheat Spectral Signal

摘要：

A method of wavelet transform is used for spectral signal processing in portable spectrometer to eliminate noise signal. An adaptive threshold method is validated in choosing threshold in this paper. Compared with traditional means, this method can eliminate noise more efficiently, and the details of signal are retained better. Simulation result proves outstanding performance of this method.
