How to do face alignment without considering eye position

If you don't want to locate eyes, you can for example use cv::matchTemplate() function. Your reference template will be an average face image. However, do you have any special reason why you don't want to locate eyes? the Haar detectors haarcascade_lefteye_2splits.xml and haarcascade_righteye_2splits.xml from opencv sample cascade classifiers work quite good for me. The further proper alignment based on the detected eyes is really easy.

Yes I know , it is easy by locating eyes. Suppose if I got image with side face at that time I can't locate eyes. That's why I am asking is it possible to do face alignment without locating any points.

Actually matchTemplate() is used for image matching. How we canc use this for face alignment????

You cannot combine face recognition for frontal and side faces together. That is just not done due the the large inner class difference (too much variation of a single person to train a decent classifier). So either split it up or just use frontal faces. I dont know why you would use profile faces for person recognition in the first place.

Is there any way to do face alignment for profile face?

You would need to train 3 seperate detectors. An ear detector, a chin detector and a profile eye detector. Then use those interesting points to align all those profile faces. But why you want to align profile faces?

can you use profile face in recognition ?

Yes you can but you will need to train a complete new setup with profile faces. Also I have no idea how good this will work.
