| 摘 要： | 针对地球观测系统/中分辨率成像光谱仪EOS/MODIS（Earth Observation System/Moderate Resolution Imaging Spectroradiometer）影像资料中的积雪检测,提出了基于支持向量机SVMs（Sup-port Vector Machines）的遥感影像分类方法。分析了积雪检测过程中的特征选择和提取,建立基于支持向量机的遥感影像分类模型,并进行了积雪检测试验。结果表明,特征选择对积雪检测起到了积极的作用,同时也证明了支持向量机方法在遥感影像分类中的优势,值得进一步推广使用。

| Abstract: | Focusing on the detection of snow cover from the image data of Earth Observation System/Moderate Resolution Imaging Spectroradiometer(EOS/MODIS),this paper introduces a new classification model of remote sensing images based on Support Vector Machines(SVMs).Firstly,the feature extraction and selection are analyzed of snow cover detection process,then a new classification method is established for remote sensing images based on SVMs,and at last a snow cover detection experiment is performed to validate the m... |
