Toward robust analysis of unstructured point-cloud

My research interests focus on the analysis of unstructured data (usually point-clouds) generated by acquiring a physical object or scene, a very hot topic in several research communities (Computer&Graphics, Pattern Recognition, …) and in the industry. Above all the research aspects, I’m considering the following challenges: 1) there is currently no practical formalism allowing to characterize shapes at locals, medium and larges scales at once, 2) the notion of a shape scale within an object is still ill-defined, despite a wide range of attempts, 3) very few studies have been published on the transitions between the pertinent scales and shapes of a 3D model.

In addition to these theoretical challenges, I’m also very interested in the applications that could be enhanced by more efficient analysis of raw point clouds: cleaning, reconstruction, abstraction, completion, recognition, etc. I’m also keeping track of the last advances in the industry, and I’m working with companies to transfer my research.


I’m looking for students, PhD students and post-doc on 3D shape analysis and processing. Open calls (master internships, doctoral fellowships) here.

I’m also open to scientific, R&D and industrial partnerships.

Feel free to contact me !
