Quaternion Sparse Discriminant Analysis for Color Face Recognition

ICME, pp. 1-6, 2018.

Cited by: 2|Views3


To reduce feature dimensions while obtaining robust classification, in this paper, we propose quaternion sparse discriminant analysis (QSDA) for color face recognition. QSDA is formulated as a quaternion sparse regression-type model. It employs the quaternion algebra to provide an elegant and holistic way to represent color face images. T...More
