Abstract :
We propose a new Tikhonov-Miller restoration method where an a priori model of the solution is included. In sharp contrast with the classical method, this approach allows local information to be incorporated. The main difficulty is to express this local information in a model. We show that this new method can lead to better results than the usual Tikhonov-Miller approach, if a parametric a priori model is used
