Research interests

The Project Team « SIgnal-Image-Modeling’’ (SIIM) is part of the Signal & Image pole of the LIS laboratory. This team is hosted in the SeaTech engineering school of the University of Toulon (La Garde site).

The researches of the members of the SIIM team are gearing towards data sciences & analysis, and concern more precisely: signal and image processing, computer vision, machine learning and optimization.

They range from the observation or the physical study of the data for modeling or characterization purposes or their processing and analysis. The main aims are to retrieve meaningful information or latent variables, to help the end-users with the interpretation of the results or to develop automatic decision or diagnostic assistance systems. This involves the development of innovative theoretical approaches and the effective implementation of these methods through numerical computation and high performance algorithms. These (dedicated) solutions also have to be able to take into account the specificities and constraints linked to the considered application. Depending on it, we can handle different kind of datasets: multidimensional or multimodal signals, multi- or hyper- spectral images, 3D or 4D fluorescence spectroscopy imaging, video sequences, etc.
