I hope u can do this by also taking nose tip's coordinate and then applying affine transform.( scale, rotation ,transation free)

thanks for your reply.can you send me some materials about face
normalization?

If you only have the nose tip, you can't correct rotation ;) Try eye
detetion in OpenCV.

If rotation is "in-plane", then it can be corrected if we are given eye and nose tip coordinates, I hope. I have not tried it, but it should be true.

Yeah, didn't get the "also", sorry :\ It's possible. OpenCV offers a
wide range of detection pattern (eyes, mouth, nose). But you need a
sufficient image quality. We just used the eyes. Worked for FERET-like
quality, but not for a standard webcam.

Hey! It is very simple. Find out required angle of rotation from the
orientation of line
joining tw
o eyeballs and then rotate the image. Simple.

Refer our paper published at Tencon 2009
