JR EAST Technical Review-No.5 The JR East Group developed an AC Train prototype (Series E993 type train) towards the formation of the next generation of commuter and suburban trains. This train was the first commuter and suburban train for the JR East Group to employ the articulated method, a method that was adopted in order to improve passenger services and reduce the life cycle cost. In contr...

In this paper we address the problem of aligning 3-D data with articulated shapes. This problem resides at the core of many motion tracking methods with applications in human motion capture, action recognition, medical-image analysis, etc. We describe an articulated and bending surface representation well suited for this task as well as a method which aligns (or registers) such a surface to 3-D...

3D articulated devices involve moving parts with significant out-of-plane motion. While manufacturing technologies exist for scaling down 2D articulated devices, a scalable and cost effective manufacturing method does not currently exist for making mesoscopic 3D articulated devices. Even though individual mesoscopic parts can be easily fabricated, assembling them into devices remains a major ch...

We present a novel optimization-based algorithm for articulated body dynamics simulation. We formulate the governing equations of rigid body dynamics using only the position variables and recast the position-based articulated dynamics as an optimization problem. We also extend our framework to handle joint limits, control forces/torques, fluid drag forces, and frictional contact forces. Our ref...

In networked virtual environments; when the participants are represented by virtual human figures, the articulated structure of the human body introduces a new complexity in the usage of the network resources; because the size of a message needed to represent the body posture is much larger than the one needed for simple, non-articulated objects. This might create a significant overhead in comm...

We present a matrix factorisation approach for 3D reconstruction of articulated objects from monocular images. Previous factorisation methods can solve for multiple independently moving objects, but fail in the articulated case because of a rank deficiency in the input matrix. By extending the shape and motion matrices used in the case of independent objects, we derive a reconstruction algorith...

Tracking articulated hand motion from visual observations is challenging mainly due to the high dimensionality of the state space. Dense sampling is difficult to be performed in such high-dimensional space, so the traditional particle filtering can’t track articulated motion well. In this paper, we propose a new algorithm by combining differential evolution with a particle filter, to track the ...

An efficient articulated body tracking algorithm is proposed in this paper. Due to the high dimensionality of human-body motion, current articulated tracking algorithms based on sampling [1], belief propagation (BP) [2], or non-parametric belief propagation (NBP) [3], are very slow. To accelerate the articulated tracking algorithm, we adapted belief propagation according to the dynamics of arti...

The correct segmentation of articulated motion is an important factor to extract and understand the functional structures of complex, articulated objects. Segmenting such body motion without additional appearance information is still a challenging task, because articulated objects as e.g. the human body are mainly based on fine, connected structures. The proposed approach combines consensus bas...

Pressure measurement devices can be classified into two groups: those where pressure is the only source of power and those that require electrical excitation. The mechanical style devices that are only excited by pressure, such as bellows, diaphragms, bourdons, tubes or manometers, are usually suitable for purely mechanical systems. With these devices a change in pressure will initiate a mechan...
