1. A method for detecting mouth corners within an image comprising: accessing texture information of a face within the image; identifying plural sets of mouth corner candidates in response to applying a plurality of different detection schemes to the texture information of the face, wherein the applying of each of the plurality of different detection schemes produces a corresponding different set of the plural sets of mouth corner candidates; and applying a geometric model to the mouth corner candidates to identify best matching mouth corners and storing the best matching mouth corners in a storage component of a device, wherein applying the geometric model comprises: determining which of the mouth corner candidates are most frequently identified by the geometric model as likely to match the mouth corners, for a plurality of different shapes of a mouth in the image, wherein the most frequently identified mouth corner candidates are identified as the best matching mouth corners.
