Quaternion Nuclear Norms Over Frobenius Norms Minimization for Robust Matrix Completion
Yu Guo, Guoqing Chen, Tieyong Zeng +2
Recovering hidden structures from incomplete or noisy data remains a pervasive challenge across many fields, particularly where multi-dimensional data representation is essential.…
Quaternion Nuclear Norm minus Frobenius Norm Minimization for color image reconstruction
Yu Guo, Guoqing Chen, Tieyong Zeng +2
Color image restoration methods typically represent images as vectors in Euclidean space or combinations of three monochrome channels. However, they often overlook the correlation…
How to Best Combine Demosaicing and Denoising?
Yu Guo, Qiyu Jin, Jean-Michel Morel +1
Image demosaicing and denoising play a critical role in the raw imaging pipeline. These processes have often been treated as independent, without considering their interactions. In…
Deep Inertia Half-Quadratic Splitting Unrolling Network for Sparse View CT Reconstruction
Yu Guo, Caiying Wu, Yaxin Li +2
Sparse view computed tomography (CT) reconstruction poses a challenging ill-posed inverse problem, necessitating effective regularization techniques. In this letter, we employ $L_p…
