Quasi Non-Negative Quaternion Matrix Factorization with Application to Color Face Recognition
Yifen Ke, Changfeng Ma, Zhigang Jia +2
To address the non-negativity dropout problem of quaternion models, a novel quasi non-negative quaternion matrix factorization (QNQMF) model is presented for color image processing…

A dynamical system based on projection operator for solving absolute value equations associated with second-order cone
Cairong Chen, Dongmei Yu, Deren Han +1
A new equivalent reformulation of the absolute value equations associated with second-order cone (SOCAVEs) is emphasised, from which a dynamical system based on projection operator…

Completing Partial Point Clouds with Outliers by Collaborative Completion and Segmentation
Changfeng Ma, Yang Yang, Jie Guo +2
Most existing point cloud completion methods are only applicable to partial point clouds without any noises and outliers, which does not always hold in practice. We propose in this…
