A nonmonotone adaptive projected gradient method for primal-dual total variation image restoration
A nonmonotone adaptive projected gradient (NAPG) method is proposed. The proposed method implements image restoration by deblurring and denoising alternatively at each iteration. The per-iteration computational complexity of the algorithm is dominated by two fast Fourier transforms (FFTs). It is competitive to some restoration functions in Matlab image processing toolbox and some state-of-the-art algorithms, such as FISTA, FTVd, and TwIST.
