| Abstract: | Discrimination of kinds,brands and origins of food products is a very active area with the application of pattern recognition techniques.The Vis-near infrared spectroscopic signals of 114 seasoning wine were measured and compressed by wavelet transform,and the Fisher ratios of 16 wavelet detail coefficients were calculated by Fisher F-ratio approach.The similarities of three different brands of seasoning wine samples were calculated by vector similarity analysis using 16 wavelet detail coefficients.Principa... |
