In this paper, a method of Gabor plus improved two-dimensional linear discriminant (Gabor+I2DLDA) which is a improved 2DLDA method by integrating the Gabor wavelet representation of palm images is proposed. Traditional two-dimensional linear discriminant (2DLDA) method eliminates the column relevance of the image, while improved 2DLDA is a direct 2DLDA method which is defined in the traditional 2DLDA...
In this paper, a method of GB2DPCA+PCA which is a bi-directional compressed 2DPCA (B2DPCA) plus PCA method by integrating the Gabor wavelet representation of palm images is proposed. The 2DPCA is a two dimensional principal component analysis method. In this approach, the Gabor wavelets are used to extract palmprint features. The B2DPCA is applied directly on the Gabor transformed matrices to remove...
