To get Kinect data there is support in VideoCapture class. So the user can retrieve depth map,
rgb image and some other formats of Kinect output by using familiar interface of \texttt{VideoCapture}.\par
To use existing support of Kinect sensor the user should do the following preliminary steps:\newline Kinect sensor is supported through \texttt{VideoCapture} class. Depth map, rgb image and some other formats of Kinect
