Abstract:

Common building extraction algorithms were mainly implemented in a fully-supervised manner, and the resulting model usually only perform well on training data sets, but operate badly on cross domain. The domain adaptation method based on generative adversarial network (GAN) can enhance the migration ability of the network to a certain extent. However, due to the lack of key information of the target domain, it is difficult to guarantee its ideal performance. A new end-to-end weakly-supervised building extraction network is proposed in this paper, which adopts pixel correlation module (PCM) to improve the performance of the generative network, and then based on this, uses two strategies, domain adaptation and image-level weak label, to optimize the training process, thereby improving the ability of generalization and expansion of the network greatly. Three datasets are used to verify the effectiveness of the proposed method. Extensive experiments show that the proposed method can effectively improve the performance of building extraction. At the same time, ablation studies are conducted to verify the effectiveness of each module in the network.

Key words: semantic segmentation, building extraction, weakly supervision, domain adaptation, generative adversarial network (GAN)
