Total variation image restoration by alternating direction method of multipliers
Zhihui Wei · Computer Engineering and Applications Journal · 2010
An alternating direction method of multipliers based fast algorithm for total variation image restoration is presented.TV model is reformulated equivalently as an equality-constrainted program by variable substitution.Then the corresponding equality-constrainted program is solved by alternating direction method of multipliers.Experimental results demonstrate the effectiveness both in the SNR value and the visual effect,compared with FTVd method.
