shotdetect - scene change detector
SYNOPSIS
shotdetect [options]
DESCRIPTION
shotdetect detects shots and scenes in a movie. The result produced is a simple XML file containing scenes boundary and features. It is
also possible to automatically get scenes boundary shots.
OPTIONS -h display help
-i file
video input file path
-o path
output directory path
-s threshold
the threshold is the level for shot detection. High will not detect a lot, low will detect a lot of false shots. A good choice is
about 60
-w generates an xml with basic audio features
-v generates an xml with basic video features
-f generates the first image of shots
-l generates the last image of shots
-m generates the thumbnails images
-r generates the real size images

linefind - Detect vertical features in images
SYNOPSIS
linefind [options] -o output.pto input.pto
DESCRIPTION
linefind is a detector for vertical features in images. It tries to find vertical lines using the same algorithm as Calibrate_lens_gui and
assigns vertical control points to them. The detection runs on the source images, if the input images are rectilinear images. In the other
cases (e. g. fisheye images) the input images are reprojected to an equirectangular projection and the detection works on the reprojected
images. It uses the roll value, saved in the pto project file, to determine what is "top" and "bottom". So before running linefind check
that your roll values are correct (E. g. when using images straight from the camera, use a roll value of 0 for landscape and a value of 90
or 270 for portrait images. If your camera has an orientation sensor, Hugin can detect this information automatically and sets the roll
value accordingly when adding such images into Hugin.
OPTIONS
-o|--output output.pto
Output Hugin PTO file. Default: '<filename>_line.pto'.
-l|--lines num
The maximum number of lines added per image (default: 5) Attention: Keep in mind that more vertical control points will dominate the
optimisation in favour of "normal" control points.
-i|--image num
Image number(s) to process. Normally linefind tries to find vertical lines in all images of the project file. If you want to limit the
detection to some selected images, you can use this parameter. Can be used multiple times.
-h|--help
