Kinect can likewise recognize shadows. The Kinect sensor uses a structured light technique to make a depth map of the scene, wherein a dot pattern is projected by an IR light projector and captured by a displaced IR camera (see Figure. fig.  7(b)). By solving the disparities of the projected dots in the middle of the IR light projector and camera, the depth of the scene is completed (see Figure. fig.  7(c)). This In this  research, \citet{deng2013kinect} considered that, they advocate a completely different thought for turning Kinect holes into useful information. In particular, we are curious in the type of holes that result from structured light shadows, which frequently occur close to the limit of the objects in the scene, Concerning an illustration, it is illustrated in Figure. fig.  7(c)&(d). Such shadow information will be exceptionally of service for giving work to high-level information of the scene.
