Road information is a crucial type of geographic information. The extraction of road information from remote sensing images has been widely applied in various fields such as mapping, transportation, and navigation. However, due to the obstruction of buildings, trees, and shadows, or the spectral similarity between roads and buildings, road extraction remains a challenging research topic. Most current methods focus only on the spatial domain, neglecting the information contained in the image frequency domain. Therefore, this work proposes a remote sensing image road extraction model, frequency domain attention encoder-decoder network (FDAENet). This model mainly consists of three parts. First, the encoder is composed of frequency domain transformer modules (FDTMs). The |
