The research team built a database of people's motions, using cable television recordings and web video downloads.
Next, they appliedmachine learning techniques to train a computer system to compare the signature of the movement of an individual in a video to that of a database of other subjects.
The so-called "GreenDot" project is federally funded by the National Science Foundation and the Office of Naval Research, and conducted by an interdisciplinary team of computer scientists, movement experts, linguists, and others.
