An ADMM-LAP method for total variation myopic deconvolution of adaptive optics retinal images
Xiaotong Chen, James L. Herring, James G. Nagy +2
Adaptive optics (AO) corrected ood imaging of the retina is a popular technique for studying the retinal structure and function in the living eye. However, the raw retinal images a…

A multi-level ADMM algorithm for elliptic PDE-constrained optimization problems
Xiaotong Chen, Xiaoliang Song, Zixuan Chen +1
In this paper, the elliptic PDE-constrained optimization problem with box constraints on the control is studied. To numerically solve the problem, we apply the 'optimize-discretize…

An FE-dABCD algorithm for elliptic optimal control problems with constraints on the gradient of the state and control
Zixuan Chen, Xiaoliang Song, Bo Yu +1
In this paper, elliptic control problems with integral constraint on the gradient of the state and box constraints on the control are considered. The optimal conditions of the prob…
