In order to avoid the staircasing effect and edge blurring problem. A variable TV
p
norm was defined
and an adaptive TV
p
(ATV
p
) regularization model was proposed. Combining the AOS numerical method
a complete ATV
p
regularization algorithm was shown
where p can be adaptive selected according to different image areas. The characteristics make the new model preserve the edge information better and avoid the staircasing effect while image restoration. Experiments showed that compared with the existing regularization models
it improved the restoration results in both visual effects and SBR and PSNR.
