Denoising for Low-Dose CT Image by Discriminative Weighted Nuclear Norm Minimization

Denoising for Low-Dose CT Image by Discriminative Weighted Nuclear Norm Minimization

Low-dose computed tomography (LDCT) is an effective approach to reduce radiation exposure to patients. Lots of mottle noise and streak artifacts, however, are introduced to the reconstructed image. Current weighted nuclear norm minimization (WNNM) denoising method cannot remove the streak artifacts...
