A New Low-Rank Learning Robust Quaternion Tensor Completion Method for Color Video Inpainting Problem and Fast Algorithms
In this paper, we present a new robust quaternion tensor completion (RQTC) model to solve this challenging problem and derive the exact recovery theory.
Quasi Non-Negative Quaternion Matrix Factorization with Application to Color Face Recognition
Numerical results indicate that the accuracy rate of face recognition on the quaternion model is better than on the red, green and blue channels of color image as well as single channel of gray level images for the same data, when large facial expressions and shooting angle variations are presented.
A contribution to condition numbers of the multidimensional total least squares problem with linear equality constraint
All expressions and upper bounds of these condition numbers unify the ones for the single-dimensional TLSE problem and multidimensional total least squares problem.

Non-Local Robust Quaternion Matrix Completion for Color Images and Videos Inpainting
A new patch group based NSS prior scheme is proposed to learn explicit NSS models of natural color images.

Sample-Relaxed Two-Dimensional Color Principal Component Analysis for Face Recognition and Image Reconstruction
A sample-relaxed two-dimensional color principal component analysis (SR-2DCPCA) approach is presented for face recognition and image reconstruction based on quaternion models.
