In this paper, a novel robust markerless image processing system capable of extracting gait features which can be used for gait analysis is presented. The presented system can deal with images of persons captured in natural indoor scenes. The system's robustness against external influences and different person appearance is achieved by employing the idea of(More)
This paper presents a method for modelling graphics scenes consisting of multiple volumetric objects. A two-level hierarchical representation is employed, which enables the reduction of the overall storage consumption as well as rendering time. With this approach, different objects can be derived from the same volumetric dataset, and 2D images can be(More)
— We introduce a new system performance measure due to handoff called handoff interference, which characterizes the additional interference noise induced by the handoff process. The handoff interference experienced by a mobile unit is determined by the parameters of the handoff algorithm. We present an exact analysis of the handoff interference and the(More)
In this paper the novel mobile robotic gait rehabilitation system CORBYS is presented. The system consists of a mobile platform and a powered orthosis attached to the platform. Beside the mobility, i.e. overground walking, due to introduced degrees of freedom (DOFs) CORBYS gait rehabilitation system, in contrast to existing gait rehabilitation robotic(More)
This paper addresses the problem of real‐time vision‐based human tracking to enable mobile robots to follow a human co‐worker. A novel approach to combine stereo vision‐based human detection with human tracking using a modified Kalman filter is presented. Stereo vision‐based detection combines features extracted from 2D stereo images with reconstructed 3D(More)
This paper addresses the problem of recognizing and reconstructing real-world objects in cluttered environments to enable service robot to grasp the objects and manipulate them. A novel approach to combine disparity segmentation method with the closed-loop color region based segmentation is presented. Disparity map segmentation leads to definition of object(More)
The number of mechanical degrees of freedom (DoFs) within rehabilitation robots directly influences the scope of the movements that a subject can perform when training walking. Currently, gait rehabilitation robots have a limited number of mechanical DoFs, as a consequence this limits the movements these robots can make possible. In this paper, the novel(More)
