Abstract:To address two key chalenges-namely,the multi-scale and multi-directional nature of roads and the frequent loss of fine-grained details,we propose a novel remote sensing road extraction network based on detail-adaptive and shallow feature guidance. Firstly,we design a shallow feature-guided attention module,which integrates strip convolutions,atention mechanisms,and shalow feature guidance to enhance the reconstruction of detailed information.Then,a multi-scale and multi-directional feature fusion module is developed,leveraging Gabor convolutions,local pooling,and global directional pooling to improve the representation of road features at various scales and directions.Finally,a detail-adaptive enhancement module is constructed using Gaussian filtering,interpolation,serpentine convolution,and standard convolution,which adaptively enhances the detailed information. The proposed network achieves F1- scores and IoU values of 74.62% and 62.38% on the CHN6-CUG dataset and 77.86% and 65.17% on the Massachusetts dataset, outperforming eight existing methods by at least 1.41% and 1.32% and 1.04% (204 and 0.88% , respectively. Compared with other advanced methods,the proposed model demonstrates superior performance in road extraction tasks,maintaining high extraction accuracy while having a lower parameter count,showing a good balance between performance and eficiency.
