Aims and objectives throughout the project<br />
The aim of this project is to develop theoretical signal processing tools to<br />
answer the need for operational surveillance of the environment. It implies<br />
supplying detection maps of "concerned targets" from satellite and/or aircraft<br />
remote sensing data : detection maps of oil spills, detection maps of change<br />
following natural disasters, maps of changes of land use and planning. In this<br />
context identified difficulties concern the processing of heterogeneous data<br />
from various sensors (multispectral or hyperspectral optic imaging, thermal,<br />
radar imaging) or from identical sensors of different modalities (geometric<br />
acquisition, wavelength, polarisation, resolution…)<br />

In 2008, as planned, the developments followed mainly two axes:<br />
1- an axis dedicated to abrupt changes, which represents the main contractual<br />
activity notably in collaboration to the CNES. But it also benefited from the<br />
CARNOT project (superTemp) thanks to which a post-doctorate student<br />
carried out, in 2008, theoretical research into the indicators of change, mainly<br />
by using a non-parametric model of signal in a sparse representation.<br />
2- An axis, dedicated to the joint processing of heterogeneous data, where<br />
parametric and non-parametric materials were proposed. The first is only<br />
applicable to the detection of change between two observations and then are<br />
involved in Major Disaster context. The latter can be applied to time series of<br />
observations dedicated to the detection of progressive changes.<br />
Emerging activities appeared in 2008 within the SISE project. Notably the<br />
characterisation of high resolution multi-component signals (for instance<br />
polarimetric radar or hyperspectral signal characterisation). On this topic the<br />
actual bibliography concerns only panchromatic signal processing.<br />
