Projected gradient descent for non-convex sparse spike estimation

no code implementations12 May 2020 Yann Traonmilin, Jean-François Aujol, Arthur Leclaire

We propose a new algorithm for sparse spike estimation from Fourier measurements.

RIU-Net: Embarrassingly simple semantic segmentation of 3D LiDAR point cloud

no code implementations21 May 2019 Pierre Biasutti, Aurélie Bugeau, Jean-François Aujol, Mathieu Brédif

This paper proposes RIU-Net (for Range-Image U-Net), the adaptation of a popular semantic segmentation network for the semantic segmentation of a 3D LiDAR point cloud.

Variational Methods for Normal Integration

2 code implementations18 Sep 2017 Yvain Quéau, Jean-Denis Durou, Jean-François Aujol

The need for an efficient method of integration of a dense normal field is inspired by several computer vision tasks, such as shape-from-shading, photometric stereo, deflectometry, etc.

Normal Integration: A Survey

1 code implementation18 Sep 2017 Yvain Quéau, Jean-Denis Durou, Jean-François Aujol

In the first part of this survey, we select the most important properties that one may expect from a normal integration method, based on a thorough study of two pioneering works by Horn and Brooks [28] and by Frankot and Chellappa [19].

Regularized Discrete Optimal Transport

1 code implementation21 Jul 2013 Sira Ferradans, Nicolas Papadakis, Gabriel Peyré, Jean-François Aujol

The resulting transportation plan can be used as a color transfer map, which is robust to mass variation across images color palettes.
