Abstract
This paper presents a new data fusion methodology named Fusion-FCN for the classification of multi-source remote sensing data using fully convolutional networks (FCNs). Three different types of data including LiDAR data, hyperspectral images and very high resolution images are utilized in the proposed framework. Considering the confusions between similar categories (e.g., road and highway), we further implement post-classification processing with the topological relationship among different objects based on the result yielded by the proposed Fusion-FCN. The proposed method achieved an overall accuracy of 80.78% and a kappa coefficient of 0.80, which ranked first in the 2018 IEEE GRSS Data Fusion Contest.
