Denoising on Textured Image Using Total Generalized Variation With Overlapping Group Sparsity Based on Fast Split Bregman Method

Autor: Cheng Zhang, Kin Sam Yen

Publikováno v: IEEE Access, Vol 12, Pp 19145-19157 (2024)

The Total Generalized Variation (TGV) model proves effective in removing texture and background patterns in natural images while suppressing the staircase effect introduced by traditional Total Variation (TV) regularization. Nevertheless, TGV falls s

A spatially variant high-order variational model for Rician noise removal

Autor: Tran Dang Khoa Phan

Publikováno v: PeerJ Computer Science, Vol 9, p e1579 (2023)

Rician noise removal is an important problem in magnetic resonance (MR) imaging. Among the existing approaches, the variational method is an essential mathematical technique for Rician noise reduction. The previous variational methods mainly employ t
