Auto-Tracking Technology
To accelerate the image data processing, an in-house program has been developed for automatic point-tracking in recorded videos. The program can automatically and efficiently record the coordinates of characteristic points frame by frame. A movie below shows the auto-tracking demo.

Testing Cases
Comparisons are made between Lucas-Kanade method (OpenCV’s built-in function) and the current method. Thirty-five points have been selected in each of the testing cases below.
Testing Result
The precision of Lucas-Kanade method is around 60 percent. In contrast, the precision obtained from the current method is around 90 percent. Especially, the current method is very powerful in tracking a rotating object.
