ADMM (The alternating direction method of multipliers is being used now a days to solve the problem of image restoration. The ADMM splits the inverse problem into small fragments. In this paper we make the use of ADMM TV algorithm to reconstruct the distributes parameters. In each iteration ...
Table 3 shows that all the involved methods can successfully reconstruct the pMRI image; PLADMM–TGV outperforms the other methods in PSNR, SSIM, and relative error, since it adopts the more efficient TGV regularization; whereas, PLADMM–TV is superior in terms of CPU time. In contrast with...

In this , we apply this approach to GPR data to reconstruct both dielectric permittivity and electrical conductivity. Numerical tests on a simple and a more realistic models confirm good performance of the ADMM-based FWI for GPR data.Note: This paper was accepted into the Technical Program but ...
