Abstract
Technologies are provided herein for determining if a face image is of sufficient quality for facial recognition processing. An image that contains a face image is received and analyzed to identify facial features of the face image. Distances between the facial features are determined and dimensions of regions for the facial features are calculated based on those distances. A plurality of regions in the face image are defined based on the calculated dimensions. A combined pixel contrast quality of the face image is then calculated based on a combination of separate pixel contrast qualities for the plurality of regions. The face image is determined to be of sufficient quality for facial recognition processing in response to the combined pixel contrast quality satisfying one or more criteria.
