Sart-Type Half-Threshold Filtering Approach for CT Reconstruction
The ℓ<sub>1</sub> regularization problem has been widely used to solve the sparsity constrained problems. To enhance the sparsity constraint for better imaging performance, a promising direction is to use the ℓ<sub>p</sub> norm (0 <; p <; 1...
