Laplacian Frequency Interaction Network for Rural Thematic Road Extraction
arXiv CS.CV
•
ArXi:2605.02866v1 Announce Type: new Rural thematic road network construction aims to extract topological road structures from movement trajectory images of agricultural machinery. However, this task faces challenges where downsampling methods commonly used in existing studies tend to blur the sparse high-frequency road structures, and the heavy noise from dense field operations often leads to fragmented or redundant topologies in the extracted networks. To address these challenges, we propose LFINet, a Laplacian Frequency Interaction Network.
