9. A method comprising: utilizing a selected portion of classifiers in detectors to determine coarse pose information for a candidate face in an image; determining fine pose information for the candidate face based at least in part on the determined coarse pose information; and employing another portion of the classifiers in the detectors to perform face detection based at least in part on the fine pose information to determine whether the candidate face corresponds to a face.
