In this paper we address the problem of predicting human body configurations and appearance for the task of humanmotion tracking in video. Unlike many previous approaches that relied on simplified body models, we are able to use detailed models of body shape. Having rendered the body model onto the current video frame, we make use of the optical flow information to propagate the body configurat...

We propose a per-frame upper body pose estimation method for sports players captured in low-resolution team sports videos. Using the head-center-aligned upper body region appearance in each frame from the head tracker, our framework estimates (1) 2D spine pose, composed of the head center and the pelvis center locations, and (2) the orientation of the upper body in each frame. Our framework is ...

A. V. Meremianin∗ Department of General Physics, Voronezh State University, 394006, Voronezh, Russia (ΩDated: February 22, 2013) Abstract The Eckart frame is used to separate out the collective rotations in the quantum three-body problem. Explicit expressions for the corresponding rotational and vibro-rotational (i.e. Coriolis) Hamiltonians are derived. Special attention is paid to the situatio...

A controller is developed for underactuated surface ships with only surge force and yaw moment available to globally track a reference trajectory generated by a suitable virtual ship in a frame attached to the ship body. The control development is based on Lyapunov’s direct method and backstepping technique, and utilizes several properties of ship dynamics and their interconnected structure. Nu...

BACKGROUND Human body communication (HBC) using the human body as the transmission medium, which has been regarded as one of the most promising short-range communications in wireless body area networks (WBAN). Compared to the traditional wireless networks, two challenges are existed in HBC based WBAN. (1) Its sensor nodes should be energy saving since it is inconvenient to replace or recharge t...

1. Body-weight, body height, knee width, wrist width and skinfold measurements were made on males (n 139) and females (n 167) in three age-groups (20-22, 25-27 and 30-32 years). Percentage of body fat was calculated from skinfold thicknesses using regression equations according to Durnin & Womersley (1974). Three indices of relative weight were calculated: W/H2, W/Hp and W/W, where W is body-we...

Nomenclature β,γ(∈ S) = The gimbal and wheel angles. (rad) Rβ(∈ SO(3)) = Transformation from gimbal frame G to the spacecraft body frame B. Is = Spacecraft inertia without the CMG gimbal and wheel inertia. (kg.m) Ig, Ir = Gimbal frame inertia, wheel inertia about own centre of mass represented in gimbal frame. (kg.m) (Igr)β = Combined inertia of gimbal frame and wheel in the spacecraft frame. R...

Body balance test is one of the methods assessing vestibular level. However, results are still qualitative, depending on subjectivity doctor. This study proposes a new, low-cost method to quantitatively determine degree body imbalance. The proposal includes laser source, proposed rectangular paper frame, camera, and computer. frame mounted patient. source fixed projected onto this frame. projec...
