Temporal sparsity exploiting nonlocal regularization for 4D computed tomography reconstruction
X-ray imaging applications in medical and material sciences are frequently limited by the number of tomographic projections collected. The inversion of the limited projection data is an ill-posed problem and needs regularization. Traditional spatial regularization is not well adapted to the dynamic...
