If i align my dataset for i need to align the faces i get from my webcam as well ? I don't think philip's example shows that although i might be wrong.

I mean if we preprocess training data we need to do the same for the images we get from our webcam, so does this apply to alignment as well?

It's not really clear from the question which OpenCV function(s) you are talking about. You might want to edit the question with a link to the function documentation/example you're talking about.

Not so much a function as more of an approach to align facial data using the eyes as an offset.

YES, you need to apply the same operations on your test data as those you applied on your training data to get the full potential of your classifier. If not it will probably work but just less accurate.
