-fast -f	<int> size (in pixels) of smallest face in frontal view that can be detected. Must be >= 20. For instance "-fast 40" accelerates search extremely. default: 20	optional
-color -c	switch; use color information of image to accelerate search; frontal faces are only searched in skin color like regions.	optional
-rotate -ro	<step angle> <# of steps in each direction> search also for rotated faces; For instance, "-ro 10 1" means that the face detector is applied to the orginal image and to the images rotated by 10 degrees clock- and counterclockwise.	optional
-report -r	switch; output detection result to file "<video_directory>/measurements/detectFacesLocations/frame#.txt"	optional
-out -o	store marked faces as JPEG images named "frame#.jpg"; only Sun Solaris	optional

By this command line the faces in frontal view (at least 40by 40 pixels large) are located in the movie ForrestGump from frame 4113 to 4500. Every 3th frame is processed. The output looks like

frame 4113 Thu Jun 4 13:28:34 1998
1 176 92 69 10
frame 4116 Thu Jun 4 13:28:42 1998
1 176 92 84 0
frame 4119 Thu Jun 4 13:28:50 1998
1 174 92 58 0
frame 4122 Thu Jun 4 13:28:58 1998
1 169 93 58 10
frame 4125 Thu Jun 4 13:29:07 1998
1 164 94 69 0
....

The output shoud be read in the following way: For each frame n which is processed "frame <no> <starting date/time of search>" is output followed by a list of localized faces. Each localized face is described in its own text line. The first integer specifies the running face number in the frame. It is followed by the position (x,y) of the face (center) and the size of the face. The last parameter specifies at which rotation angle the face was detected.
