In this paper, we propose a new time dependent model for solving total variation (TV) minimization problems in image restoration. We present a proof of the existence, uniqueness and stability of the viscosity solution of our model. The results from our new model by explicit numerical schemes are compared with the results from those models introduced by several image researchers by simple and significant 2D numerical experiments. Experimental results demonstrate that our new model can get better results than the existing models.
