Currently, angle two-dimensional principal component analysis (Angle 2DPCA) effectively enhances the robustness of traditional 2DPCA by using a measurement model based on F-norm in the relationship between reconstruction error and variance, and successfully applied in image feature extraction. However, ...

Facial symmetry is a helpful characteristic, which benefits of feature extraction. In this paper, Mirror Principal Component Analysis (Mirror PCA) method is proposed for extracting representative facial features, which takes advantage of the facial symmetry in a face image. In order to verify the ...

However, such a vectorization has been proved not to be beneficial for image recognition due to consequences of both the algebraic feature extraction approach and 2DPCA. In this paper, inspired by the above two approaches, we try an opposite direction to extract features for any vector pattern ...

In this paper, two-dimensionalprincipal component analysis (2DPCA) is used forimage representation and recognition. Compared to1D PCA, 2DPCA is based on 2D image matricesrather than 1D vectors so the image matrix does notneed to be transformed into a vector prior to featureextraction. Instead,...
For a real-world database containing n frontal face images A1,A2,…,An, we normalize the pixel values of each image to [0,1] and resize all the images to 50×40. Then, the right half of each image Recognition experiments on real-world databases In this section, we test the qualities...
