Alternating Minimization Algorithm for Poissonian Image Restoration |
|

Abstract:To quickly remove Poisson noise, based on the traditional alternating direction method, this paper combined the relaxation method and proposed an improved alternating minimization algorithm. Compared with the classical numerical algorithm, numerical simulations demonstrate that the proposed strategy not only removes Poisson noise efficiently, but improves the speed of calculation substantially and reduces the computer CPU time noticeably. |
