Abstract: In the field of remote sensing, the method of realizing image semantic segmentation by using a large amount of label image data to supervise training full convolution network will result in expensive label drawing cost, while the use of a small amount of label data would lead to network performance degradation. To solve this problem, this paper proposes a semi-supervised full convolution network based semantic segmentation method for high resolution remote sensing images. Specifically, we explore an ensemble prediction technique to train the end-to-end semantic segmentation network by simultaneously optimizing a standard supervised classification loss on labeled samples along with an additional unsupervised consistence loss term imposed on labeled and unlabeled data. In the experiments, the image data set of Vaihingen in Germany provided by ISPRS and satellite GF-1 data were used, and the experimental results show that the proposed method can effectively improve the network performance degradation caused by using only a small amount of label data.
