YANG Wankou, JI Shanbing, REN Mingwu, YANG Jingyu. Face Extraction Based on Enhanced 2DPCA and Its Application to Face Recognition[J]. Journal of Image and Graphics, 2009, 14(2): 227-232. DOI: 10.11834/jig.20090207.
called Enhanced two-dimensional principal component analysis (2DPCA)
is proposed in this paper
which uses 2DPCA operated in the row direction and alternative 2DPCA operated in column direction. Enhanced 2DPCA can compress image in row and column direction. Enhanced 2DPCA needs fewer coefficients for image representation than 2DPCA does. The experimental results on the ORL and FERET database show that the Enhanced 2DPCA can work well and surpass two-directional two-dimensional principal component analysis((2D)2PCA).
