Eigenface algorith can be improved!

This paper suggests that discarding the three most significant principal components, the variation due to lighting is reduced, then Eigenface gives better output. Q1: does somebody can suggest how to do so, or even are we able to modify the Opencv code to remove three components of PCA ? Another suggestion to be able to update the model incrementally, we can apply an incremental PCA algorithm for this purpose.

Q2: is it possible to do so on OpenCV code?
