In this talk, we introduce a fast multilevel method for solving minimization problems arising in various image restoration problems. Different from traditional multilevel methods which solve the the minimization problems by considering their Euler-Lagrange equations, here our multilevel method directly minimizes the functionals. We will illustrate the method in various denoising and deblurring problems.
