Quaternion Optimized Model with Sparse Regularization for Color Image Recovery
Liqiao Yang, Yang Liu, Kit Ian Kou
This paper addresses the color image completion problem in accordance with low-rank quatenrion matrix optimization that is characterized by sparse regularization in a transformed d…
A Robust Lane Detection Associated with Quaternion Hardy Filter
Wenshan Bi, Dong Cheng, Kit Ian Kou
In this article, a robust color-edge feature extraction method based on the Quaternion Hardy filter is proposed. The Quaternion Hardy filter is an emerging edge detection theory. I…
A Robust Color Edge Detection Algorithm Based on Quaternion Hardy Filter
Wenshan Bi Dong Cheng Wankai Liu, 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…
Facial Expression Classification Using Rotation Slepian-based Moment Invariants
Cuiming Zou, Kit Ian Kou
Rotation moment invariants have been of great interest in image processing and pattern recognition. This paper presents a novel kind of rotation moment invariants based on the Slep…
