LDPoly: Latent Diffusion for Polygonal Road Outline Extraction in Large-Scale Topographic Mapping
LDPoly jointly generates road masks and vertex heatmaps with a dual-latent diffusion model, then polygonizes them into compact road outlines that beat prior methods on Dutch topographic benchmark Map2ImLas.
