Age estimation is an important method to solve the face recognition with age change, due to the feature extraction,in the process of age estimation study, PCA dimensional reduction method is usually used to reduce dimension with excessive dimension.PCA refers that transform the sample matrix into one-dimensional vector first, then the one-dimensional vectors form a matrix, solve the eigenvector. 2D-PCA applied in this paper is not required to transform the sample matrix into one-dimensional vector, but construct scatter matrix with data matrix directly, accordingly, the computing time is reduced and a good performance evaluation is achieved in the test.
PCA generally refers that transform the sample matrix into a one-dimensional vector first, then a number of the sample vectors form a matrix[4], finally solve the eigenvectors of the covariance matrix; 2D-PCA is not required to transform the sample matrix into a one-dimensional vector, but construct scatter matrix with data matrix directly,therefore, characteristics extracted by 2D-PCA are better and faster than PCA and the calculation time is reduced.
Compare with PCA and 2D-PCA dimension reduction method of the face image identification and the calibration point method, the time spent and the recognition rate were as shown in Figure 1.
Randomly select the training sample, the rest are as test sample, treat with PCA and 2DPCA dimension reduction. 3.
