摘要

针对全色CCD光学遥感卫星成像，提出了一种基于多属性融合的高分辨率遥感图像云检测方法。首先，根据物理特征和成像特征提取特征参数，提出可分度的概念进行特征选择;然后，根据样本的分布差异，引入LDA算法对特征空间进行降维;最后，利用支持向量机分类器进行云检测。实验结果表明，该方法适用于不同成像平台的高分辨率全色遥感图像，检测概率高，虚警概率低，效率高。

A method for cloud detection in high-resolution remote sensing image based on multi-attribute fusion

For panchromatic CCD optical remote sensing satellite imaging,a cloud detection method in high-resolution remote sensing image based on multi-attribute fusion is proposed.First,according to the physics and imaging features,the feature parameters are extracted,and a concept of separable degree is proposed for feature selection.Then,according to the distribution differences of the samples,the LDA algorithm is brought for reducing the dimension of the feature space.At last,a SVM classifier is used for cloud detection.The experimental results show that the proposed method is suitable for high-resolution panchromatic remote sensing image with different imaging platform,and it has a high detection probability and a low false alarm probability,and a high efficiency.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
