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…
SimpliCity: Reconstructing Buildings with Simple Regularized 3D Models
Jean-Philippe Bauchet, Raphael Sulzer, Florent Lafarge +1
Automatic methods for reconstructing buildings from airborne LiDAR point clouds focus on producing accurate 3D models in a fast and scalable manner, but they overlook the problem o…
Concise Plane Arrangements for Low-Poly Surface and Volume Modelling
Raphael Sulzer, Florent Lafarge
Plane arrangements are a useful tool for surface and volume modelling. However, their main drawback is poor scalability. We introduce two key novelties that enable the construction…
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.…
