A Fast Incremental Multilinear Principal Component Analysis Algorithm
نویسندگان
چکیده
This study establishes the mathematical foundation for a fast incremental multilinear method which combines the traditional sequential Karhunen-Loeve (SKL) algorithm with the newly developed incremental modified fast Principal Component Analysis algorithm (IMFPCA). In accordance with the characteristics of the data structure, the proposed algorithm achieves both computational efficiency and high accuracy for incremental subspace updating. Moreover, the theoretical foundation is analyzed in detail as to the competing aspects of IMFPCA and SKL with respect to the different data unfolding schemes. Besides the general experiments designed to test the performance of the proposed algorithm, incremental face recognition system was developed as a real-world application for the proposed algorithm.

Multilinear principal component analysis for face recognition with fewer features
In this study, a method is proposed based on multilinear principal component analysis (MPCA) for face recognition. This method utilized less features than traditional MPCA algorithm without downgrading the performance in recognition accuracy. The experiment results show that the proposed method is more suitable for large dataset, obtaining better computational efficiency. Moreover, when support...
