| 摘 要： | 从支持向量机的基本理论出发,结合高光谱数据的分离性测度,提出了一种基于分离性测度的二叉树多类支持向量机分类器,并用OMIS传感器获得的高光谱遥感数据和Hyperion高光谱遥感数据进行实验,分析比较了各种多类SVM的分类精度,并和传统的光谱角制图和最小距离分类算法进行了比较。结果表明,SVM进行高光谱分类时,基于分离性测度的二叉树多支持向量机的分类精度最高。

| Abstract: | According to SVM theory and the separability measure of hyperspectral data,we put forward a novel binary tree multi-class SVM classifier based on separability between different classes,constructed different multi-class SVM classifiers and tested their accuracy by experimented the hyperspectral image with the 64 bands OMISII data and Hyperion hyperspectral data.The experimental results show that the novel binary tree classifier has the highest accuracy than the other multi-class SVM classifiers and some trad... |
