The Algorithm for Image Deblurring Based on Smoothing Absolute Value Function
A convex smooth deblurring model is presented which combines the edge information of the image and absolute value smoothing technique.Based on the TV and Tikhonov hybrid regu-larization model,the smoothing function is employed to approximate the TV regularization term of the hybrid model,which makes it a smooth and convex optimization problem,and it is solved by the semi-proximal alternating direction method of multipliers(SPADMM)algorithm.Numerical experi-mental results on different fuzzy kernels and Gaussian noise levels show that our algorithm can not only effectively eliminate noise and blur,but also retain the image edge information better.
