An Algorithm of l(1)-Norm and l(0)-Norm Regularization Algorithm for CT Image Reconstruction from Limited Projection
The l(1)-norm regularization has attracted attention for image reconstruction in computed tomography. The l(0)-norm of the gradients of an image provides a measure of the sparsity of gradients of the image. In this paper, we present a new combined l(1)-norm and l(0)-norm regularization model for ima...
