Saliency-based football offside detection

摘要

In the automatic offside detection for football, an afterimage and occlusion sometime confuse the referee which cause a judging error. This paper proposes an automatic saliency-based offside detection method. Four cameras are installed at the both sides on the centerline for capturing scenes of players with a ball. In the scenes, offensive players who are playing the ball are estimated their movement by saliency, and the estimated motion is compared with the position of the defensive players for determining offside. The experiments performed video with 138 times offside in 33 tournaments of FIFA world football competitions held in Europe in 2016, and the results show 93.33% accuracy.
