Bloch

Isabelle Bloch has been a lecturer and researcher at Télécom Paris since 1991. She is currently working on the mathematical modeling of spatial relations and on spatial reasoning within the LTCI (IMAGES team).

She builds mathematical models, which are then integrated into algorithms to assist in the interpretation of images, particularly medical images. In this field of application, the researcher proposes methods to help doctors analyze and interpret images. To do this, she models the spatial relationships between objects, then integrates them into processes of analysis and interpretation to guide segmentation, i.e. to determine the contours or surfaces of the various objects in an image, and the recognition of objects (organs or pathologies), by restricting the search area.

Therefore she deals mostly with spatial reasoning, developed using mainly algebraic methods (mathematical morphology, fuzzy sets, logic). This research has many applications, mainly in medical imaging, with notably, in close collaboration with university hospitals, help for diagnosis and therapeutic or surgical planning – by allowing less invasive surgery, follow-up in time, etc.

The reasercher has previously worked on information fusion, or how to combine various information from images of different origins of the same problem and improve decision making about the object of observation. This work on fusion is now part of the information processing in several fields, including ongoing work in medical imaging and spatial reasoning.

Recently, Isabelle Bloch has begun a prospective collaboration with researchers at Ircam (Institut de Recherche et Coordination Acoustique/Musique) in order to extend the spatial representation tools she is developing to consider ramifications in the spatial representation of music.
She received the Blondel Medal in 2008, which rewards each year the exceptional work of a young scientist.
