Description:
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.
