Binary package “facedetect” in ubuntu focal

simple face detector for batch processing

 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.
