Building extraction from remote sensing images with deep learning in a supervised manner

摘要

Building extraction from remote sensing images is a longstanding topic in land use analysis and applications of remote sensing. Variations in shape and appearance of buildings, occlusions and other unpredictable factors increase the hardness of automatic building extraction. Numerous methods have been proposed during the last several decays, but most of these works are task oriented and lack of generalization. This paper applys deep learning to building extraction in a supervised manner. A deep deconvolution neural network with 27 Convolution/Deconvolution weight layers is designed to realize building extraction in pixel level. As such a deep network is prone to overfitting, a data augment method that suits pixel-wise prediction tasks in remote sensing is suggested. Moreover, an overall training and inferencing architecture is proposed. Our methods are finally applied to building extraction tasks and get competitive results with other methods published.
