In this paper, the classic TV-L1 model is extended to a hybrid TV-L1 model based on first order and second order derivatives to remove image noises, preserve geometry, contrast and overcome staircase effects.To improve efficiency, a fast algorithm based on dual method which is called the Split-Dual algorithm is designed for the model.Finally, the denoising quality and the computational time between the proposed algorithm and some other traditional methods are compared.
