Cluster Experiments:

This movement signature distance matrix indicates that Hillary Clinton, Ellen DeGeneres, and David Letterman form one cluster, Angela Merkel and the Pope form another cluster, and Nicolas Sarkozy, Barack Obama and Jon Stewart form a third cluster in the space of movement signature styles.

Here are some example frames of the database used to train the system:

Recognition Performance:

If our system only observes the video (and no audio), on videos that the system has not seen before (i.e., an independent test set), it will average 80% correct identification. If it also uses audio, it is 95% correct.

We published many reports about these new findings here
