@ -28,9 +28,9 @@ To do the tracking we need a video and object position on the first frame.
You can download our example video and data from
[here](https://docs.google.com/file/d/0B72G7D4snftJandBb0taLVJHMFk).
To run the code you have to specify input and output video path and object bounding box.
To run the code you have to specify input (camera id or video_file). Then, select a bounding box with the mouse, and press any key to start tracking
