摘　　要：以集安地区林下山参为实验材料,应用Matlab 2014a数字图像处理工具箱,从林下山参的芦、体、纹、须入手,对不同生长年限的林下山参图像信息进行处理,提取林下山参形状特征、纹理特征共11个数字化特征信息,建立数据库模型,摸索不同生长年限林下山参特征的变化规律,以支持向量机对选取的林下山参进行生长年限判别。结果表明,建立的数据库模型较为稳定,林下山参生长年限判别率平均为88.75%,为进一步研究不同产地林下山参生长年限的识别奠定基础。Image informations of mountain cultivated ginseng with different growth periods were processed using the matlab 2014 a software box in order to identify mountain cultivated ginseng in Ji＇an using a digital method. Based on the shape,color and texture features,11 image informations from ginseng rhizome,body,grain,peel,fibrous root were extracted and a digital mountain cultivated ginseng database model was established. It was found that the recognition rate of ginseng was 88. 75%. The results could lay the foundation to identify mountain cultivated ginseng with different growth periods.
