The P Dataset: Pixels, Points and Polygons for Multimodal Building Vectorization
Raphael Sulzer, Liuyun Duan, Nicolas Girard +1
We present the P dataset, a large-scale multimodal benchmark for building vectorization, constructed from aerial LiDAR point clouds, high-resolution aerial imagery, and vectori…
3D detection of roof sections from a single satellite image and application to LOD2-building reconstruction
Johann Lussange, Mulin Yu, Yuliya Tarabalka +1
Reconstructing urban areas in 3D out of satellite raster images has been a long-standing and challenging goal of both academical and industrial research. The rare methods today ach…
SCR: Smooth Contour Regression with Geometric Priors
Gaetan Bahl, Lionel Daniel, Florent Lafarge
While object detection methods traditionally make use of pixel-level masks or bounding boxes, alternative representations such as polygons or active contours have recently emerged.…
