Constrained low-rank quaternion approximation for color image denoising by bilateral random projections
Jifei Miao, Kit Ian Kou
In this letter, we propose a novel low-rank quaternion approximation (LRQA) model by directly constraining the quaternion rank prior for effectively removing the noise in color ima…
Quaternion Hardy Functions for Local Images Feature Representation
Xiaoxiao Hu, Kit Ian Kou, Yangxing Ting
This paper is concerned with the applications of local features of the quaternion Hardy function. The feature information can be provided by the polar form of the quaternion Hardy…
Quaternion matrix regression for color face recognition
Jifei Miao, Kit Ian Kou
Regression analysis-based approaches have been widely studied for face recognition (FR) in the past several years. More recently, to better deal with some difficult conditions such…
Low-rank quaternion tensor completion for recovering color videos and images
Jifei Miao, Kit Ian Kou, Wankai Liu
Low-rank quaternion tensor completion method, a novel approach to recovery color videos and images is proposed in this paper. We respectively reconstruct a color image and a color…
A Robust Color Edge Detection Algorithm Based on Quaternion Hardy Filter
Wenshan Bi, Dong Cheng, Kit Ian Kou
This paper presents a robust filter called quaternion Hardy filter (QHF) for color image edge detection. The QHF can be capable of color edge feature enhancement and noise resistan…
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…
