Clothes change detection using the Kinect sensor

This paper describes a methodology for detecting when a human has changed clothes. Changing clothes is a basic activity of daily living which makes the methodology valuable for tracking the functional status of elderly people, in the context of a non-contract unobtrusive monitoring system. Our approach uses Kinect and the OpenNI SDK, along with a workflow of basic image analysis steps. Evaluation has been conducted on a set of real recordings under various illumination conditions, which is publicly available along with the source code of the proposed system at http://users.iit.demokritos.gr/ tyianak/ClothesCode.html.
