3D human motion tracking is in recent years the field of machine vision is a very important research direction, it has a wide range of applications, such as human-computer interaction, intelligent animation, video surveillance and other. Currently about three-dimensional human motion tracking research mostly based multicast video, monocular video due to the depth information of the lack of the ...

3D motion tracking is a critical task in many computer vision applications. Existing 3D motion tracking techniques require either a great amount of knowledge on the target object or specific hardware. These requirements discourage the wide spread of commercial applications based on 3D motion tracking. 3D motion tracking systems that require no knowledge on the target object and run on a single ...

Accurate video-based ball tracking in team sports is important for automated game analysis, and has proven very difficult because the ball is often occluded by the players. In this paper, we propose a novel approach to addressing this issue by formulating the tracking in terms of deciding which player, if any, M is in possession of the ball at any given time. This is very different from standar...

We report a portable 6-DOF (six degrees of freedom) motion tracking system which uses high-accuracy AR markers. It enables easy measurement of 6-DOF motion of multiple tracking points by a single camera. We examined the measurement accuracy of the motion tracker by comparing with an ordinary motioncapture system. The pose estimation errors are about 5 [mm] in location (depth) and about 2 [deg] ...

We address global motion planning for quasi-static reorientation of convex objects (polyhedral and smooth objects) with a four-fingertip grasp. We make use of a simple humanlike manipulation strategy in which a single finger is moved at each instant while the other three are maintained fixed (with regard to the palm)—an extended version of the original finger-tracking scheme of Rus. This new ve...

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...

In this case study we discuss an interactive feature tracking system and its use for the analysis of chromatin decondensation. Features are described as points in a multidimensional attribute space. Distances between points are used as a measure for feature correspondence. Users can interactively experiment with the correspondence measure in order to gain insight in chromatin movement. In addit...

This paper presents a real-time hybrid solution to articulated 3D arm motion tracking for home-based rehabilitation by combining visual and inertial sensors. The Extended Kalman Filter (EKF) is used to fuse the different data modalities from two sensors and exploit complementary sensor characteristics. Due to the non-linear property of the arm motion tracking, upper limb geometry information an...
