Swimmer’s Head Detection Based on a Contrario and Scaled Composite JTC Approaches

<div>Lane extraction and mask application taking into account the four points: <i>x</i><sub>1</sub>, <i>x</i><sub>2</sub>, <i>x</i><sub>3</sub>, and <i>x</i><sub>4</sub>. The metric coordinates of these points are known and pixel coordinates are calculated using the calibration results. Swimming Championships in Limoges, France, April 2015.</div>
