Constrained [Formula: see text] Minimization for Enhanced Exploitation of Gradient Sparsity: Application to CT Image Reconstruction
Exploiting sparsity in the image gradient magnitude has proved to be an effective means for reducing the sampling rate in the projection view angle in computed tomography (CT). Most of the image reconstruction algorithms, developed for this purpose, solve a nonsmooth convex optimization problem invo...
