I'm looking for software to automatically track a ball in a video stream. Think tracking a tennis ball, against a fairly plain background. So the input would be a video stream, and the output is a set of coordinates of the tracked ball. The camera would be fixed. Ideally, you'd be able to do this in realtime.
I'm sure this is a pretty standard thing (I've seen it done!) but I can't find any packages that do it, probably because I don't know what phrase to search for.
I want to run the software on a Windows PC.
What is this sort of thing called? Motion tracking? Image tracking? Object tracking?
Can anyone reccomend any packages that do this?
Thanks in advance,
Jim
