Abstract :
This paper proposes a new approach for the reconstruction of the RS images degraded by composite noise (additive and multiplicative), taking into account the limitations of the sensor system. Our proposal takes advantage of the statistical and probabilistic qualities of the employed weighted constrained least squares (WCLS) and robust Bayes minimum risk (RBMR) algorithms. The restoration of the image optimized by aggregating the WCLS, RBMR, the maximum entropy and variational analysis techniques.
