SwimTrack: Swimmers and Stroke Rate Detection in Elite Race Videos

We present SwimTrack, a series of 5 multimedia tasks related to swimming video analysis from elite competition live recordings. These tasks are related to video, image, and audio analysis which may be achieved independently. But when solved altogether, they form a grand challenge to provide sport federations and coaches with novel methods to asses and enhance swimmers' performance, in particular related to stroke rate and length analysis. We share a unique collection of video footage that contains all swimming race types, recorded from a spectator point of view with variations such as lighting reflections, background clutter, noise from the motion of waves, and different point of views on swimmers. SwimTrack is the first challenge of this kind for a total of 4 swimming elite competitions. We sought to include a larger and even more diverse set of videos as well as additional mini-challenges once more recordings will be available in a next version
