Position of People without Skeleton [closed]

edit

When using programs such as NiUserTracker, a person's body is recognized before it is actually being tracked. This is apparent because the entire body is covered with a certain color, representing which user it is, before the skeleton is applied. Is there a way to get the position of a user in this state? I am loading calibration data, so the skeletons do not always fit perfectly. Also, this would greatly increase speed.
