Total Variation Superiorized Conjugate Gradient Method for Image Reconstruction
Marcelo V. W. Zibetti, Chuan Lin, Gabor T. Herman
The conjugate gradient (CG) method is commonly used for the rapid solution of least squares problems. In image reconstruction, the problem can be ill-posed and also contaminated by…
