Limited-angle CT reconstruction via the L1/L2 minimization
Chao Wang, Min Tao, James Nagy +1
In this paper, we consider minimizing the L1/L2 term on the gradient for a limited-angle scanning problem in computed tomography (CT) reconstruction. We design a specific splitting…

Accelerated Schemes for the Minimization
Chao Wang, Ming Yan, Yaghoub Rahimi +1
In this paper, we consider the minimization for sparse recovery and study its relationship with the - model. Based on this relationship, we propose three nu…
