                           video

positional arguments:
  video                 relative/absolute path to video or camera input of
                        traffic scene

optional arguments:
  -h, --help            show this help message and exit
  --iscam               specify if video capture is from a camera
  --droi DROI           specify a detection region of interest (ROI) i.e a set
                        of vertices that represent the area (polygon) where
                        you want detections to be made (format:
                        1,2|3,4|5,6|7,8|9,10 default: 0,0|frame_width,0|frame_
                        width,frame_height|0,frame_height [i.e the whole video
                        frame])
  --showdroi            display/overlay the detection roi on the video
  --mcdf MCDF           maximum consecutive detection failures i.e number of
                        detection failures before it's concluded that an
                        object is no longer in the frame
  --mctf MCTF           maximum consecutive tracking failures i.e number of
                        tracking failures before the tracker concludes the
                        tracked object has left the frame
  --di DI               detection interval i.e number of frames before
                        detection is carried out again (in order to find new
                        vehicles and update the trackers of old ones)
  --detector DETECTOR   select a model/algorithm to use for vehicle detection
                        (options: yolo, haarc, bgsub, ssd, tfoda | default:
                        yolo)
  --tracker TRACKER     select a model/algorithm to use for vehicle tracking
                        (options: csrt, kcf, camshift | default: kcf)
  --record              record video and vehicle count logs
  --headless            run VCS without UI display
  --clposition CLPOSITION
                        position of counting line (options: top, bottom, left,
                        right | default: bottom)
