  In this work, we propose a swimming analytics system for automatically
determining swimmer stroke rates from overhead race video (ORV). General ORV is
defined as any footage of swimmers in competition, taken for the purposes of
viewing or analysis. Examples of this are footage from live streams,
broadcasts, or specialized camera equipment, with or without camera motion.
These are the most typical forms of swimming competition footage. We detail how
to create a system that will automatically collect swimmer stroke rates in any
competition, given the video of the competition of interest. With this
information, better systems can be created and additions to our analytics
system can be proposed to automatically extract other swimming metrics of
interest.
