1. A digital image acquisition device, comprising a lens and image sensor for acquiring a digital image, a processor, and memory having code embedded therein for programming the processor to perform a method of determining a state of a facial feature, wherein the method comprises: acquiring a digital image; detecting a face region within the acquired digital image; determining an orientation of the face region; extracting and rotating a crop of the face region, thereby providing a normalized face crop; applying at least one set of classifiers to said normalized face crop; and based on results of said applying at least one set of classifiers to said normalized face crop, determining a state of at least one facial feature within said normalized face crop.
