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.
