Hi! I am a researcher at IGN, the French National Geographical Institute, in the machine learning team STRUDEL (LaSTIG, Univ. Gustave Eiffel). I am interested in optimization and machine learning for spatially structured data such as 3D point clouds or satellite images time-series analysis.
See my academic_CV for more details (updated in Sept 2021).
I am the main investigator of the ReADy3D ANR project on Dynamic 3D. I am also co-program chair of the XXIVth ISPRS congress in Nice in 2022.
Checkout our open seminar on Nov 10 on Deep Learning for Environment Monitoring!
NEW! Our paper on unsupervized and visual representation of large shape collections has been accepted at 3DV 2021 arXiv project
NEW! Our paper on panoptic segmentation of satellite time series, with Vivien Sainte-Fare Garnot has been accepted at ICCV 2021. Preprint. Check out PASTIS: the first SITS panoptic-ready dataset.
NEW! Our paper on scalable deep surface reconstruction, with Raphael Sulzer, Renaud Marlet, and Bruno Vallet has been accepted at Eurographics SGP 2021. Preprint.
NEW! Our CVPR Workshop EarthVision have been accepted. Great line-up of speakers, contests, and as always a must for meeting remote-sensing researchers interested in the latest advances in computer vision.
NEW! Our ISPRS Special Issue « Muti-modal learning in photogrammetry and remote sensing« , co-edited with Michael Ying Yang, Devis Tuia, and Charles Toth is online. Some very interesting work about a hot topic.
NEW! Our paper presenting Torch-points3D havs been accepted as an oral at 3DV 2020. Congrats to the awesome dev team for their impressive work.
NEW! Our newest paper on satellite time series with Vivien Sainte-Fare Garnot has been accepted at CVPR 2020 for an oral! Check the paper and the code.
