Experiment I.

• 2D histograms of player position,cumulative histograms of absolute position error:

• Combined (color + template tracking) method performed better than background subtraction.

• Wide FIR filter decreases error in path length - heavy smoothing preferred.

RMS position error:

0.18 - 0.50 m (still)

0.28 - 0.63 m (active)

Path length error:

0.6 - 1 m/player/min (still)

6 - 10 m/player/min (active)
