Change detection of marine reclamation using multispectral images via patch-based recurrent neural network

Marine reclamation plays an increasingly important role in expanding living space, which should be monitored to ensure legitimate development. In this paper, a patch-based recurrent neural network is developed for change detection of marine reclamation. To capture spatial difference of image patches in two images, a patch-based recurrent neural network is proposed to extract features, where patches from two multispectral images are stacked as a sequence for inputting. After training the deep network, Softmax classifier is applied to detect the changed region. It is illustrated that our network can obtain the difference of two images to improve detection accuracies. Experiments on the study area of the Jinzhou Bay demonstrate that the proposed method outperforms other approaches.
