Journal ArticleDOI
Low-dose spectral CT reconstruction using image gradient ℓ0-norm and tensor dictionary.
TL;DR: The results show that the proposed ℓ 0TDL method outperforms other competing methods, such as total variation (TV) minimization, TV with low rank (TV+LR), and TDL methods.
Journal ArticleDOI
Non-Local Low-Rank Cube-Based Tensor Factorization for Spectral CT Reconstruction
TL;DR: Zhang et al. as mentioned in this paper proposed a non-local low-rank cube-based tensor factorization (NLCTF) method to enhance the capability of image feature extraction and spatial edge preservation.
Journal ArticleDOI
Spatial-spectral cube matching frame for spectral CT reconstruction
TL;DR: A spectral CT reconstruction method, namely spatial-spectral cube matching frame (SSCMF), inspired by the following three facts, which shows that the SSCMF method outperforms the state-of-the-art algorithms, including the simultaneous algebraic reconstruction technique, total variation minimization,total variation plus low rank, and tensor dictionary learning.
Journal ArticleDOI

Qian Wang,Yining Zhu,Hengyong Yu +2 more
TL;DR: This work establishes a locally linear relationship between the decomposed results ofDSCT and SSCT and proposes an optimization model for DSCT and develops an iterative method with image guided filtering based on the relative total variation regularization.
Journal ArticleDOI
