TV model is one of the models with the quality of preserving edges in image denoising.In order to avoid the staircasing effect from the TV model,and make the restored image have a better visualization,the L2-model is used to extract a smooth primal sketch from the observed image and then to obtain other meaningful signal by the TV model from the removed noise image.

Key words: image denoising, L2-model, TV model, staircasing effect
