1. An apparatus for detecting an occluded face, the apparatus comprising: a smoothing unit smoothing a facial region of an image; a region division unit dividing the smoothed facial region into a first region and a second region; a first region detection unit generating a first region detection result by detecting whether the first region is an occluded region; a second region detection unit generating a second region detection result by detecting whether the second region is an occluded region; and a decision unit deciding whether the facial region is an occluded face based on the first region detection result and the second region detection result.
