 We collect data using the Kinect SDK over a period of a week in a research
 laboratory setting.  The Kinect is placed at the tee of a frequently used
-hallway.  The view of the Kinect is seen in \fref{fig:hallway}, showing the
-color image, the depth image, and the fitted skeleton of a person in a single
-frame.  Skeletons are fit from roughly 1-5 meters away from the Kinect.  For each
-frame where a person is detected and a skeleton is fit we capture the 3-D
-coordinates of 20 body joints, and the color image.
