Road segmentation plays an important role in many applications, such as intelligent transportation system and urban planning. Various road segmentation methods have been proposed for visible remote sensing images, especially the popular convolutional neural network-based methods. However, high-accuracy road segmentation from high-resolution visible remote sensing images is still a challenging problem due to complex background and multiscale roads in these images. To handle this problem, a hybrid convolutional network (HCN), fusing multiple subnetworks, is proposed in this letter. The HCN contains a fully convolutional network, a modified U-Net, and a VGG subnetwork; these subnetworks obtain a coarse-grained, a medium-grained, and a fine-grained road segmentation map. Moreover, the HCN uses a shallow convolutional subnetwork to fuse these multi-grained segmentation maps for final road segmentation. Benefitting from multi-grained segmentation, our HCN shows impressing results in processing both multiscale roads and complex background. Four testing indicators, including pixel accuracy, mean accuracy, mean region intersection over union (IU), and frequency weighted IU, are computed to evaluate the proposed HCN on two testing data sets. Compared with five state-of-the-art road segmentation methods, our HCN has higher segmentation accuracy than them.
