To overcome the shortcomings of traditional dimensionality reduction algorithms, incremental tensor principal component analysis ITPCA based on updated-SVD technique algorithm is proposed in this paper. This paper proves the relationship between PCA, 2DPCA, MPCA, and the graph embedding framework theoretically and derives the incremental learning procedure to add single sample and multiple samples in detail. The experiments on handwritten digit recognition have demonstrated that ITPCA has achieved better recognition performance than that of vector-based principal component analysis PCA, incremental principal component analysis IPCA, and multilinear principal component analysis MPCA algorithms. At the same time, ITPCA also has lower time and space complexity.
