Improved Two-Dimensional Quaternion Principal Component Analysis
IEEE Access, 2019 The two-dimensional quaternion principal component analysis (2D-QPCA) is first improved into abstracting the features of quaternion matrix samples in both row and column directions, being the generalization ability, and with the components weighted by ...

Morphological Principal Component Analysis for Hyperspectral Image Analysis
ISPRS International Journal of Geo-Information, 2016 This article deals with the issue of reducing the spectral dimension of a hyperspectral image using principal component analysis (PCA). To perform this dimensionality reduction, we propose the addition of spatial information in order to improve the ...
