The hybrid trace features (HTF), a new face representation, is proposed for face authentication system. Trace transforms of multiple Trace functionals are used to construct the HTF, and Genetic Algorithms is implemented as the data fusion tool. In addition, rotation based hybrid trace features (r-HTF) is also introduced as facial features. The systemic evaluations on Cambridge ORL face database reveal that HTF and r-HTF present high discriminatory power and outperform the features extracted by principal component analysis (PCA), linear discriminant analysis (LDA) and kernel PCA in the task of classification.
