Automatic Road Extraction with Multi-Source Data Revisited: Completeness, Smoothness and Discrimination
Summary: End-to-end revisit of multi-source road extraction: dual encoders fused with attention to enhance inter-source complementarity, plus an edge-prediction auxiliary task to yield smoother, continuous road masks. Introduces pixel-aware contrastive learning to suppress road-like false positives and a model-agnostic auxiliary-task pretraining to boost accuracy; validated on real datasets.
