Get the average Image.

Get or set the eigen distance threshold. The smaller the number, the more likely an examined image will be treated as unrecognized object. Set it to a huge number (e.g. 5000) and the recognizer will always treated the examined image as one of the known object.

Get the eigen vectors that form the eigen space

Get the eigen values of each of the training image

Get or set the labels for the corresponding training image
