Welcome to the TITANE group at Inria!

Our research activities focus on geometric modeling and processing, on remote sensing, and on related areas such as image processing and computer vision. Our overall objective is the computerized geometric modeling of complex scenes from physical measurements. On the geometric modeling and processing pipeline, this objective corresponds to steps required for conversion from physical to effective digital representations: analysis, reconstruction and approximation.
