Jeudis du Cerege : The reality, the image and the model

Sophie Viseur member of the Resources, Reservoirs and Hydrosystems team.

In geosciences, images and models are widely used as a support for the understanding and  interpretation of a reality or the synthetic communication of a complex notion. In this presentation, it is a question to take you on a trip around research themes relying on images and models. The first trip concerns the "image ranking". The objective is to classify images, here geological sections, for the request of images considered as similar in their content. This work relies on artificial intelligence methods and required to develop distances between images and to define an "arithmetic" of structural geology, through a formal grammar. The second trip will take you at a small scale to simulate distributions of coccoliths. Coccoliths are small platelets produced by small organisms, the coccolithophores. The simulation aims to better understand their distribution interpretations. Finally, the last trip takes you between reality and model, the Virtual Reality, for visiting space, terrestrial fields or under.
