Boosting MR Image Impulse Noise Removal With Overlapping Group Sparse Fractional-Order Total Variation and Minimax Concave Penalty

Autor: Wei Xue, Yumeng Ge, Xiaolei Gu, Xuan Qi, Tao Tao

Publikováno v: Image Analysis and Stereology, Vol 43, Iss 1 (2024)

The acquisition and transmission of magnetic resonance images are susceptible to noise, particularly impulse noise. Although the method based on the ℓ0-norm and overlapping group sparse total variation (ℓ0-OGSTV) is effective for impulse noise im

Magnetic Resonance Image Denoising Based on Laplacian Prior Sparsity Constraint and Nonconvex Second-Order TV Penalty

Autor: Yumeng Ge, Wei Xue, Yun Xu, Jun Huang, Xiaolei Gu

Publikováno v: Image Analysis and Stereology, Vol 42, Iss 2, Pp 119-132 (2023)

Magnetic resonance (MR) imaging is considered as a very powerful imaging modality in clinical examination, but the process of image acquisition and transmission will be affected by noise, resulting in the degradation of imaging quality. In this paper

Magnetic resonance image restoration via least absolute deviations measure with isotropic total variation constraint

Autor: Xiaolei Gu, Wei Xue, Yanhong Sun, Xuan Qi, Xiao Luo, Yongsheng He

Publikováno v: Mathematical Biosciences and Engineering, Vol 20, Iss 6, Pp 10590-10609 (2023)

This paper presents a magnetic resonance image deblurring and denoising model named the isotropic total variation regularized least absolute deviations measure (LADTV). More specifically, the least absolute deviations term is first adopted to measure
