Simon Giraudot

I am currently doing a PhD at INRIA Sophia Antipolis, in the Titane team, under he supervision of Pierre Alliez. I am working on problematics related to surface reconstruction from defect-laden data (presence of noise, outliers, variable sampling or holes in the data).

Conferences and workshops I attended

Journées de Géométrie Algorithmique 2013: from December 16 to December 20 in Marseille, France.

The conference is aimed at researchers and students interested in the applicative and algorithmic aspects of geometry and topology. The format features mini courses as well as contributed talks and time for discussion. For this year, the course topics include topological aspects of the motion planning problem, tropical geometry, image processing and approximation algorithms for clustering.

EUROGRAPHICS Symposium on Geometry Procesing 2013: from July 3 to July 5 in Genova, Italy.

The Symposium on Geometry Processing (SGP) 2013, a Eurographics symposium in cooperation with ACM Siggraph, will be held from July 3 to 5 in Genova, Italy, organized by the Institute of Applied Mathematics and Information Technology of the CNR.

Journées de Géométrie Algorithmique 2012: from April 2 to April 6 in Cluny, France.

La géométrie algorithmique a pour objet l’étude, la conception et l’analyse d’algorithmes et de structures de données qui permettent de résoudre efficacement des problèmes de nature géométrique. De tels problèmes apparaissent dans divers domaines d’application tels que : informatique graphique, imagerie médicale, usinage, robotique, vision, conception assistée par ordinateur (CAO), bioinformatique, etc.

Les Journées de Géométrie Algorithmique rassemblent régulièrement la communauté française de chercheurs en géométrie algorithmique et de domaines connexes. Largement ouvertes aux jeunes chercheurs et régulièrement fréquentées par des industriels elles permettent aux chercheurs :

New Trends in Applied Geometry 2012: from February 12 to February 17 in Villa Cagnola, Italy.

This is a focused meeting, intended to bring together a small number of leading research groups in applied geometry, i.e. geometric design, geometry processing and discrete differential geometry. It follows two highly successful workshops in Bad Herrenalb, Germany (2010) and Hurdal, Norway (2011).

We aim to follow the structure of the previous meetings; a slot of two hours for each group with two slots each morning and on one afternoon. The other afternoons are free for working groups, discussions, or leisure. We expect a lively exchange of new ideas and excellent networking opportunities for the upcoming generation of researchers in the field.

Conferences I was a staff-member of

ALGO 2013: from September 2 to Septembre 6 in Sophia Antipolis, France.

ALGO is the major European meeting of researchers and students in algorithms, bringing together several hundred participants.

ALGO is an annual meeting combining the European Symposium on Algorithms (ESA) and a number of more specialized conferences and workshops.

ALGO 2013 will be hosted by Inria and Campus SophiaTech, in Sophia Antipolis, France.

Programming

NASR

NASR is an implementation of the algorithm in the paper Noise-Adaptive Shape Reconstruction from Raw Point Sets (see above).

It uses the libraries CGAL and Eigen. It is distributed as a free software under GPL license (see LICENSE file for details).

Download NASR 1.0 (source code - 42.2 kio)

Poclorage

POCLORAGE means POint CLOud RAndom GEnerator. It is a small free software (shared under the GPL licence) that can be used to simulate laser scans on generic simple shapes such as spheres, torus, cylinders, cubes, etc. It is written in C and only uses the standard library (should work on every platform with a C compiler - Windows, Mac, etc. - but was developed and only tested on a GNU/Linux environment).

I developed this tool for the needs of my PhD thesis: to test the algorithms of surface reconstruction, it is often useful to execute them on generic point clouds before using real data. I hope this can be helpful for other people.

The program randomly samples point uniformly on some predefined shapes and store them in the XYZ format. All the parameters (lengths of the generated object, number of points, key of the Pseudo Random Number Generator, etc.) can be easily user-modified with the correct arguments (see README file or --help / -h argument).

This is the very first version of the program, it seems to work fine but may contain bugs (if you found one, feel free to send me an e-mail). More improvement may come later (again, you can read the README file for more information).
