Nonconvex weighted variational metal artifacts removal via convergent primal-dual algorithms
Lianfang Wang, Zhangling Chen, Zhifang Liu +4
Direct reconstruction through filtered back projection engenders metal artifacts in polychromatic computed tomography images, attributed to highly attenuating implants, which furth…
A Fast Minimization Algorithm for the Euler Elastica Model Based on a Bilinear Decomposition
Zhifang Liu, Baochen Sun, Xue-Cheng Tai +2
The Euler Elastica (EE) model with surface curvature can generate artifact-free results compared with the traditional total variation regularization model in image processing. Howe…
-regularized Variational Methods for Sparse Phase Retrieval
Yuping Duan, Chunlin Wu, Zhi-Feng Pang +1
We study the problem of recovering the underlining sparse signals from clean or noisy phaseless measurements. Due to the sparse prior of signals, we adopt an L0regularized variatio…
A general framework for denoising phaseless diffraction measurements
Huibin Chang, Stefano Marchesini
We propose a general framework to recover underlying images from noisy phaseless diffraction measurements based on the alternating directional method of multipliers and the plug-an…
