Abstract: This paper describes a new visual representation of motion
that is used to learn and classify body language - what
we call .body signatures. - of people while they are talking.
We applied this technique to several hours of internet
videos and television broadcasts that include US politicians
and leaders from Germany, France, Iran, Russia, Pakistan,
and India, and public figures such as the Pope, as well as
numerous talk show hosts and comedians. Dependent on the
complexity of the task, we show up to 80% recognition performance
and clustering into broader body language categories.
