不同生长年限林下山参的数字图像处理研究

摘要

Image informations of mountain cultivated ginseng with different growth periods were processed using the matlab 2014a 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 informa-tions from ginseng rhizome ,body ,grain ,peel ,fibrous root were extracted and a digital mountain cultivated ginseng database model was estab-lished .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 .%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。
