train() clears the entire model, and starts from scratch.

you probably wanted to call update() instead.

now the problem is when i am authenticating

if you really want to authenticate a single user, then it's the wrong algorithm (it does identification, not authentification)

yea ok i meant prediction, now am in a possition to save one yml file and append new faces, I am saving with the labels. My challange is when predicting I am passing the image to be predicted, label and confidence. In this lbph algorithm, the label passed is -1 now confused if this label I should pass the label i set during training? Kindly assist me there.
