英文摘要 | Clouds play a significant role in weather forecasts, water cycle, and climate system. However, existing methods ignore the relations of ground-based cloud images. In this letter, we propose a novel method named task-based graph convolutional network (TGCN) for ground-based cloud classification, which takes image relations into consideration. To this end, we construct the graph using convolutional neural network-based features of ground-based cloud images which are learned in a supervised manner, and incorporate the graph computation into TGCN. Given that existing ground-based cloud databases are with limited labeled training images and categorized according to different classification criteria, we release the largest ground-based remote sensing cloud database (GRSCD) to provide a comparative study for different methods and to further improve the study of regional sky conditions. The experimental results on GRSCD manifest the effectiveness of TGCN for ground-based cloud classification. ©2020. American Geophysical Union. All Rights Reserved. |
