num_components
- The number of components (read: Fisherfaces) kept for this Linear
Discriminant Analysis with the Fisherfaces criterion. It's useful to keep all components, that
means the number of your classes c (read: subjects, persons you want to recognize). If you leave
this at the default (0) or set it to a value less-equal 0 or greater (c-1), it will be set to the
correct number (c-1) automatically.threshold
- The threshold applied in the prediction. If the distance to the nearest neighbor
is larger than the threshold, this method returns -1.
