Hi everyone,

My name is Tom Wu and I am a PhD student from
University of Alberta, Canada. I would like to find
out the center of a ball during its flight path. The
ball will be spinning so I can't simply put a marker
at the center of the ball. I use APAS software in our
lab but unfortunatley I can't change the size of the
cursor into an appropriate box size; otherwise, I'd be
able to digitize the center of the ball simply by
placing the ball in the cursor box. Does anyone have
any previous experience in tracking center of an
object? Any help is greatly appreciated!

Best regards,

Tom Wu, Prov. PhD Candidate
