1. Now having the time measurements from the video and ball world coordinates application can calculate your serve speed with a great accuracy, most times way better than a commercial speed gun (see doppler effect cosine factor error)!

4. “Tennis Serve Tracker” measures tennis serve speed using video processing and image recognition technologies.
5. Why is it worth trying it when there are similar apps on market? Because all these apps can be split on 2 categories - first are the ones that do it very, very bad or simply invent measured speed and won’t be mentioned here at all.

7. It allows to reconstruct 3D world coordinates of the server and ball from the image coordinates.
8. Application provides constant feedback by highlighting court lines, net and a ball on the screen.
