Abstract: The ecological restoration of the quarry area is an important link to improve the function of the regional ecosystem. Identifying the quarry and determining the boundary of the mining area are the prerequisites for completing the restoration task. Currently, the semantic segmentation technology based on deep learning can accurately recognize the objects of interest in high-resolution remote sensing images, providing an effective way for quarry identification. Based on the CycleMLP framework, this paper uses the pyramid structure to input multi-level features into a lightweight MLP decoder, aggregates feature information from different levels, and obtains local and global features at the same time. The convolutional layers are embedded into the feed-forward network, which avoids the accuracy decline caused by position-encoded interpolation. Experiments employ the semantic segmentation dataset of the quarry areas in Nan'an city, Fujian province to train the network and verify the accuracy. The results show that the improved CycleMLP can effectively identify quarry areas from high-resolution remote sensing images. Compared with other methods based on self-attention mechanism, the improved CycleMLP achieves higher accuracy, accurately extracts the boundary of the quarry area, and can provide reliable supporting materials for the restoration of the ecosystem in the quarry area.
