Semisoft Generalized Total Variation Minimization for Image Reconstruction in Computed Tomography

Semisoft Generalized Total Variation Minimization for Image Reconstruction in Computed Tomography

The generalized l<sub>1</sub> greedy algorithm was recently proposed and shown to outperform the standard reweighted l<sub>1</sub>-minimization and l<sub>1</sub>-greedy algorithms for image reconstruction in computed tomography (CT). Herein, this algorithm is exte...
