Abstract
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.
