For that I train Eigenfaces / Fisherfaces with 1000 Photos of 1000 different people (so 1 Photo each person). So I also have 1000 labels in the training set. Now I can use the predict method to get the most similar face. WebFeb 1, 2001 · In the context of the appearance-based paradigm for object recognition, it is generally believed that algorithms based on LDA (Linear Discriminant Analysis) are superior to those based on PCA (Principal Components Analysis).
