Abstract :
The technology of near-infrared spectroscopy analysis plays a very important role in quality detection of farm produce. This thesis analyzed grainy wheat quality with 900 nm-1700 nm wave raster near-infrared spectroscopy analysis system, filtered signal with wavelet packet analyses system, disposed signal with second order differential equipment, built and contrasted models of partial least square (PLS) and support vector machines (SVM). The results showed that the near-infrared spectroscopy analysis system can suit farm produce quality analysis well.
