%X In this paper, we propose a new time
dependent model for solving total variation (TV) minimization problem in
image denoising. The main idea is to apply a priori smoothness on the solution
image. This is a constrained optimization type of numerical algorithm for
removing noise from images. The constraints are imposed using Lagrange¡¯s
multipliers and the solution is obtained using the gradient projection method.
1D and 2D numerical experimental results by explicit numerical schemes are
discussed.
