How good are cheap depth cameras, namely the Microsoft Kinect, compared to state of the art Time-of-Flight depth cameras? In this paper several depth cameras of different types were put to the test on a variety of tasks in order to judge their respective performance and to find out their weaknesses. We will concentrate on the common area of applications for(More)
Background subtraction is a common first step in the field of video processing and it is used to reduce the effective image size in subsequent processing steps by segmenting the mostly static background from the moving or changing foreground. In this paper previous approaches towards background modeling are extended to handle videos accompanied by(More)
For a few years cameras have been available which are able to provide depth values gained from a PMD chip through the Time-of-Flight principle. Recently, cameras combining a normal color chip with such a PMD chip in a monocular setup have been developed. One drawback of these 2D/3D cameras is that the resolution of the depth images is much lower than those(More)
In this paper a tracking approach designed to utilize multiple cameras with optional depth information, e.g., ToF cameras, structured light cameras and stereo or multi camera setups, is discussed which combines photometric tracking with volumetric tracking. It is able to work with any number and type of cameras. In order to achieve this objective the(More)
