Claim 11:
12. A system for recording motion of a subject and parsing recorded image data into sets of frames that represent different behaviors of the subject, the system comprising:
a three-dimensional video camera configured to output video image data representing the motion of the subject;
a memory in communication with the three-dimensional video camera and having a non-transitory machine-readable storage medium with a machine-executable instruction set stored thereon; and
a control system comprising one or more processors coupled to the memory, the one or more processors configured to execute the machine-executable instruction set to cause the control system to:
process frames obtained using the video image data, the frames representing the motion of the subject, using a model-free algorithm to output a first and a second set of modules, wherein each module in the first set of modules exhibits pose dynamics for 200-900 milliseconds, and each module in the second set of modules exhibits pose dynamics for 200-900 milliseconds; and
identify repeated modules of the subject's behavior using a template matching procedure for matching motifs of the subject's motion.
