A Nonmonotone Gradient Algorithm for Total Variation Image Denoising Problems
The total variation (TV) model has been studied extensively because it is able to preserve sharp attributes and capture some sparsely critical information in images. However, TV denoising problem is usually ill-conditioned that the classical monotone projected gradient method cannot solve the proble...
