       This manpage was written by Andreas Tille for the Debian distribution and can be used for any other usage
       of the program.

       Facedetect  is  a  simple  face detector for batch processing. It answers the basic question: "Is there a
       face in this image?" and gives back either an exit code or the coordinates of each detected face  in  the
       standard output.

       The aim is to provide a basic command-line interface that's consistent and easy to use with software such
       as ImageMagick, while progressively improving the detection algorithm over time.

       facedetect  is  used  in software such as fgallery to improve the thumbnail cutting region, so that faces
       are always centered.
