Toward robust analysis of unstructured point-cloud
I am a CNRS researcher, working at the STORM research group, in the IRIT laboratory, Toulouse.
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 large 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. I’ve also a growing interest on color processing, using geometrical properties of colors. We call that Structural Color Processing.
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 are listed on our group webpage.
I’m also open to scientific, R&D and industrial partnerships.
