摘要: 本文将Fmask云检测结果作为标记样本对深度卷积神经网络进行训练以实现云检测。在仅利用可见光波段和近红外波段的前提下,本文方法的云检测总体精度达到87.65%,高于Fmask的86.92%,而且单景Landsat 8影像的识别用时18 s,远低于Fmask的72 s,具有更高的精度和效率。另外,该方法适用于不同的地表土地覆盖类型,具有很强的泛化能力,是一个通用性强的算法,为进一步的遥感应用打下基础。

Abstract: This paper introduces Fmask cloud detection results as training label into the deep convolutional neural network (DCNN) for cloud detection. Under the premise of using only the visible light band and the near infrared band, the overall accuracy of cloud detection method in this paper reaches 87.65%, which is higher than 86.92% of Fmask. It costs 18 seconds for processing a single Landsat 8 image, which is much lower than 72 seconds that Fmask costing. In addition, this method is suitable for various type of land cover in target image, and has a strong generalization ability for further application.

Key words: cloud detection, deep convolutional neural network, Fmask, Landsat 8, strong generalization ability
