To compute the Fisherfaces, we assume the data in each class is Normally distributed. We denote the multivariate Normal distribution as with mean and covariance matrix and its probability density function is In the class problem, we have with Given these Normal distributions and their class prior … See more The theoretical argument given in the preceding section shows how to obtain the Bayes optimal solution for the 2-class homoscedastic case. In general, we will have more than 2-classes. In such a case, we reformulate the … See more P. Belhumeur, J. Hespanha, and D. Kriegman, Eigenfaces vs. Fisherfaces: Recognition Using Class Specific Linear Projection, IEEE … See more To obtain the Fisherfaces, we need to compute the inverse of i.e., If the sample feature vectors are defined in a -dimensional space … See more Recently, Two-dimensional LDA (2DLDA), a tensor extension of LDA, is proposed. Different from the LDA which requires the input patterns to be converted to one-dimensional vectors, the 2DLDA directly extracts the proper … See more WebJun 1, 2024 · The Fisherface algorithm is considered an evolution of the Eigenface algorithm [41].
