Motion-Capture Trace Motif

Two motion-capture traces played as animation simultaneously. While the right-hand punch is nearly identical in both moves, the boxer in the top trace is throwing a right cross. In contrast, the boxer in the bottom trace is throwing a one-two combo.  The motion-capture data is from CMU Graphics Lab Motion Capture Database (link).

Recall in the paper, we have the following statement: Let revisit the toy example shown in Fig. 2, with the number of random walk time series set to four in addition to the two random walks that have an embedded motif. We note in passing that even this simple and small example is not trivial for humans to process. The following figure is an example generated based on the statement. Can you spot the embedded motifs? Click the figure to see the location of the embedded motif.
