Some of the problems involved in social measurement include the lack of universally accepted theoretical frameworks and thus of quantifiable measures, sampling errors, problems associated with the intrusion of the measurer on the object being measured, and the subjective nature of the information received from human subjects. Problem of human parts detection, pose estimation and human detection using depth information by kinect distance map the matching measure is determined by the.
