Optical tracking stabilization using low-pass filters

Optical tracking usually depends on adequate, good and stable lighting conditions. If the lighting conditions become unstable and often changing, the results are usually an unstable optical tracking and a jumping of the superimposed image. In this article, we propose low-pass filters for the stabilization of the superimposed image and for the compensation of jittering effects while performance, robustness and accuracy of the optical tracking system is not influenced.
