Abnormal Markers Detection in Motion Capture System Based on the Revised L^2 Depth

In this paper, we present a method based on the revised L
²
depth to detect the abnormal markers in the motion capture system. Firstly, we propose the definition of the revised L
²
depth, and the algorithm of the depth is also presented. Secondly, the algorithm of detection using the derivatives of the markers' trajectories is discussed. The results in the experiment shows the validity of the method.
