In the case that the person is not wearing a helmet - does his face pose is frontal?

Camera position doesn't seems to give the frontal face pose.

You can use Hough Circle Transform. But the minRadius size and maxRadius size may vary with the images. Its tough to get the accurate result and false detection will be higher. Else there is no such algorithm to detect "Helmet" in particular.
