SInES Tools: Point Tracking Tool
(Track up to 8 points of interest in videos, based on OpenCV.js with Kanade-Lucas-Tomasi Feature Tracker KLT)

1. Click on "Start" to set all values on default.
2. Upload an mp4 video file showing a moving object.
3. Make sure that the background in the video is as neutral as possible and contrasts strongly in color with the object
     to be tracked.
4. Click on the object to be tracked and mark it with up to eight points.
     You may name the points in the input fields as you please.

  Point 1: X: 0 Y: 0
Point 5: X: 0 Y: 0
  Point 2: X: 0 Y: 0
Point 6: X: 0 Y: 0
  Point 3: X: 0 Y: 0
Point 7: X: 0 Y: 0
  Point 4: X: 0 Y: 0
Point 8: X: 0 Y: 0
     The points can be reseted with
5. optional: Set the KLT Window Size (larger tracks = faster movements, but is less precise):
      21 (21 pixels is a good standard).
6. optional: If you know the exact frame rate of the video, you can enter/correct it here:
      fps. (Otherwise, rely on the frame rate calculated by the app).
7. optional: Set the KLT Max Pyramid Level (higher value handles larger movements):
      2 (2 or 3 is a good standard).
8. Click on "Analyse" and play the video to the end.
 9. optional: View data in the plot
10. Click on "Show JS Arrays" or "Export CSV" to show the recorded data as Javascript arrays or to export them as a
     CSV/Excel file.
