Discrimination of Ophiopogon Japonicus from Different Origions by Hyperspectroscopy Combined with Support Vector Machine
The identification method of Ophiopogon japonicus from different origions was established by hyperspectroscopy combined with support vector machine.The hyperspectral datas of Ophiopogon japonicus samples from five different origions were collected,and the hyperspectral datas were preprocessed by Savitzky-Golay smooth derivative,and then the classification model of Ophiopogon japonicus origions was established by combined with support vector machine.The results show that the classification accuracy of the model after pretreatment can reach 93.00%.The research shows that hyperspectral technique combined with support vector machine was a promising method for the identification of Ophiopogon japonicus.
