Concise Plane Arrangements for Low-Poly Surface and Volume Modelling

2 code implementations9 Apr 2024 Raphael Sulzer, Florent Lafarge

We introduce two key novelties that enable the construction of plane arrangements for complex objects and entire scenes: an ordering scheme for the plane insertion and the direct use of input points during arrangement construction.

3D detection of roof sections from a single satellite image and application to LOD2-building reconstruction

no code implementations11 Jul 2023 Johann Lussange, Mulin Yu, Yuliya Tarabalka, Florent Lafarge

We here propose a method for urban 3D reconstruction named KIBS(\textit{Keypoints Inference By Segmentation}), which comprises two novel features: i) a full deep learning approach for the 3D detection of the roof sections, and ii) only one single (non-orthogonal) satellite raster image as model input.

SCR: Smooth Contour Regression with Geometric Priors

no code implementations8 Feb 2022 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.

Finding Good Configurations of Planar Primitives in Unorganized Point Clouds

no code implementations CVPR 2022 Mulin Yu, Florent Lafarge

We present an algorithm for detecting planar primitives from unorganized 3D point clouds.

Road Extraction from Overhead Images with Graph Neural Networks

no code implementations9 Dec 2021 Gaetan Bahl, Mehdi Bahri, Florent Lafarge

By contrast, we propose a method that directly infers the final road graph in a single pass.

Planar Shape Detection at Structural Scales

no code implementations CVPR 2018 Hao Fang, Florent Lafarge, Mathieu Desbrun

Interpreting 3D data such as point clouds or surface meshes depends heavily on the scale of observation.

KIPPI: KInetic Polygonal Partitioning of Images

no code implementations CVPR 2018 Jean-Philippe Bauchet, Florent Lafarge

Recent works showed that floating polygons can be an interesting alternative to traditional superpixels, especially for analyzing scenes with strong geometric signatures, as man-made environments.


Line Drawing Interpretation in a Multi-View Context

no code implementations CVPR 2015 Jean-Dominique Favreau, Florent Lafarge, Adrien Bousseau

Many design tasks involve the creation of new objects in the context of an existing scene.

Image Partitioning Into Convex Polygons

no code implementations CVPR 2015 Liuyun Duan, Florent Lafarge

The over-segmentation of images into atomic regions has become a standard and powerful tool in Vision.

Recovering Line-Networks in Images by Junction-Point Processes

no code implementations CVPR 2013 Dengfeng Chai, Wolfgang Forstner, Florent Lafarge

Our experiments on a variety of problems illustrate the potential of our approach in terms of accuracy, flexibility and efficiency.
