Method, apparatus and computer program product for providing face pose estimation

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.

A computer program product comprising at least one computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising:

• program code instructions for utilizing a selected portion of classifiers in detectors to determine coarse pose information for a candidate face in an image;
• program code instructions for determining fine pose information for the candidate face based at least in part on the determined coarse pose information;
• and
• program code instructions for 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.
