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)
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)
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)
Interaction with mobile consumer devices leads to a higher acceptance and affinity of persons to natural user interfaces and perceptional interaction possibilities. New interaction modalities become accessible and are capable to improve human machine interaction even in complex and high risk environments, like the operation room. Here, manifold medical(More)
