摘  要:
为实现外观相似的不同玉米品种的有效识别,提出了K-L变换与最小二乘支持向量机相结合的籽粒品种鉴别方法。采用标记算法及多尺度小波分析方法获得玉米单籽粒图像,应用K-L变换技术提取籽粒图像的特征数据,设计了二叉树型多类LS-SVM分类器,实现了对特征数据的有效分类。通过试验分析,确定了较为合理的状态空间维数(L=3),正确识别率可达95.3%。

摘  要:
A method for maize cultivars identification was proposed,by using the combination algorithm of K-L transform and least square support vector machines(LS-SVM).Firstly,labeling algorithm and multi-scale wavelet analysis were used to acquire single corn kernel images;secondly,K-L transform was employed to extract the features of corn kernel images;at last,the method of LS-SVM with a binary tree architecture was developed to identify maize cultivars by using feature data.According to the result of test,the reasonable state space dimension(L=3) is acquired,and this method gives a correct recognition rate of 95.3%.
