Quickly annotate videos with bounding boxes for use in training object detectors and trackers. Keyboard commands for ease of navigation.

• Make sure video-annotation is your root folder in MATLAB, and add all subfolders to path.
• Videos go in data/videos
• Bounding boxes will be saved in data/positive_examples

Use convert_to_MAT.m to convert your video file to a matfile. Make sure to configure the correct paths

The main file is KeyboardAnnotationSimple.m, which contains usage instructions.

• g: move forward a frame in the video
• f: move backward a frame in the video
• q: quit
• t: Track: If the current frame has a bounding box, This command will track the bounding box for the next k frames. If there is no bounding box in the current frame, then this command erases all the subsequent frames contiguous to the current one. You can change k by typing:
  • 1: changes k to 10
  • 2: changes k to 20
  • 3: changes k to 30
  • 4: changes k to 40
  • 5: changes k to 50
  • 6: changes k to 60
  • 7: changes k to 70
  • 8: changes k to 80
  • 9: changes k to 90
• a: Annotate: Clicking onto the image counts as erasing the bounding box.
