In this technical demonstration, we show the application of our research on body soft biometrics. Exploiting a 3D video sensor we are able to extract semantic information that describes subjects standing in front of a camera. Semantic analysis and tracking is performed, a series of anthropometric measures are extracted and used to compute subjects' height, weight, and gender information. Possible applications of such research fall in the medical domain for monitoring elderly people; in the gaming industry for automatic avatar creation, or in smart billboards which collects demographics of the public interested by the commercial. Our algorithm allows the estimation of all these parameters in real time without requiring the computational complexity of a 3D model fitting approach.
