This thesis deals with estimation and supervised detection issues in hyperspectral imagery, applied in coastal environments. Bathymetric models of reflectance are used for modeling the water column influence on the incident light. Various parameters are optically active and are responsible for distorting the reflectance spectrum (phytoplankton, colored dissolved organic matter...). We adopt a new statistical approach for estimating these parameters, which are usually retrieved by inverting physical models. Various methods such as maximum likelihood estimation, maximum a posteriori estimation, and Cramér-Rao bound calculation, are successfully implemented on simulated and real data. Moreover, we adapt the frequently used supervised detectors...
