Future robots are expected to cooperate with humans in daily activities. Efficient cooperation requires new techniques for transferring human skills to robots. In this paper, we present a system that provides a robot with the ability to imitate a motion by observing how a human instructor conducts it. The system consists of the following modules: data acquisition, feature extraction and trackin...

introduction: the use of multiple cameras for motion analysis and single joint motion is very difficult and needs high technology in laboratory conditions. detection of single joint motion in kinesthesia and analysis of its changes can be done by one camera at one direction. in this study, we present the validity and reliability of a new prototype simulator system used for motion analysis appli...

Background: A method to track liver tumor motion signals from fluoroscopic images without any implanted gold fiducial markers was proposed in this study to overcome the adverse effects on precise tumor irradiation caused by respiratory movement. Materials and Methods: The method was based on the following idea: (i) Before treatment, a series of fluoroscopic images corresponding to different bre...

For creating real-time animations of 3D characters we introduce an animation engine for the dynamic creation of motions with motion models. Each motion models represents a small task like walk or wave and has its own set of parameters controlling the specific characteristics of a motion. The style and the characteristics of motion models can be changed in realtime. For this purpose pre-produced...

We present a system that generates arm dancing motion to new music tracks, based on sample motion captured data of dancing to other pieces of music. Rather than adapting existing motion, as most music-animation systems do, our system is novel in that it analyzes both the supplied motion and music data for certain characteristics (eg. melodic contour, loudness, etc), and learns relationships bet...

Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is f...

Single-cell recording studies have provided vision scientists with a detailed understanding of motion processing at the neuronal level in non-human primates. However, despite the development of brain imaging techniques, it is not known to what extent the response characteristics of motion-sensitive neurons in monkey brain mirror those of human motion-sensitive neurons. Using a motion adaptation...

The effects of roll on the free-flight yawing motion of statically stable test models, having linear force and moment characteristics, are discussed in more detail than in previous publications. The correspondence between the damping, frequency, and amplitude of the nutational and precessional vectors which define the motion is listed. Limitations in the use of simplified data reduction procedu...
