In the domain of Astronomy, impressive progress have been achieved these recent years by considering, at a very fundamental level, the acquisition process by the devices, and by driving the image analysis accordingly. Nowadays, algorithms must be able to merge information of different nature, and take into account the ever increasing number of spectral bands available, and use this dimensionality in the merging processes. Moreover signals in radioastronomy are now multifield and multiscale, they measure synchronously many different vectorial measures at increasing spatial resolution. In GEOSTAT, we will study data coming from the MUSE intrument (Multi Unit Spectroscopic Explorer), a 3D spectro-imager operating in the visible domain, which will become one of the instruments in the Very Large Telescope (VLT). We propose the development of methods that will take into account the specific aspects of the instrument, for instance the large dimensionality of voxels cubes produced ((300 × 300 pixels and 4096 channels), the variability of the impusional response both spatially and spectrally, and the combination of multiple pauses. GEOSTAT will also define research lines in the following areas:
