Color image recovery using low-rank quaternion matrix completion algorithm
Jifei Miao, Kit Ian Kou
As a new color image representation tool, quaternion has achieved excellent results in color image processing problems. In this paper, we propose a novel low-rank quaternion matrix…
Quaternionic left eigenvalue problem: a matrix representation
Wankai Liu, Kit Ian Kou
This paper presents an innovative set of tools developed to support a methodology to find the left eigenvalues of order quaternion square matrix. It is solving four real polyno…
Discrete Uncertainty Principle in Quaternion Setting and Application in Signal Reconstruction
Yan Yang, Kit Ian Kou, Cuiming Zou
In this paper, the uncertainty principle of discrete signals associated with Quaternion Fourier transform is investigated. It suggests how sparsity helps in the recovery of missing…
Floquet Theory for Quaternion-valued Differential Equations
Dong Cheng, Kit Ian Kou, Yong Hui Xia
This paper describes the Floquet theory for quaternion-valued differential equations (QDEs). The Floquet normal form of fundamental matrix for linear QDEs with periodic coefficient…
