Computer puppetry maps the movements of a performer to an animated character in real time. In this paper, we provide a comprehensive solution to the problem of transferring the observations of the motion capture sensors to an animated character whose size and proportion may be different than the performer. Our goal is to map as much of the important aspects of the motion to the target character as possible, while meeting the on-line, real-time demands of computer puppetry. We adopt a Kalman filter scheme that addresses motion capture noise issues in this setting. We provide the notion of dynamic importance of an end-effector that allows us to determine what aspects of the performance must be kept in the resulting motion. We introduce a novel inverse kinematics solver that realizes these important aspects within tight real-time constraints. Our approach is demonstrated by its application to broadcast television performances. 1

In this paper, we present an integrated framework of on-line motion blending for locomotion generation. We first provide a novel scheme for incremental timewarping, which always guarantees that the time goes forward. Combining the idea of motion blending with that of posture rearrangement, we introduce a motion transition graph to address on-line motion blending and transition simultaneously. Guided by a stream of motion specifications, our motion synthesis scheme moves from node to node in an on-line manner while blending a motion at a node and generating a transition motion at an edge. For smooth on-line motion transition, we also attach a set of example transition motions to an edge. To represent similar postures consistently, we exploit the inter-frame coherency embedded in the input motion specification. Finally, we provide a comprehensive solution to on-line motion retargeting by integrating existing techniques. Copyright # 2004 John Wiley & Sons, Ltd.

By Hyun Joon Shin ∗ and Jehee Lee Human motion is difficult to create and manipulate because of the high dimensionality and spatiotemporal nature of human motion data. Recently, the use of large collections of captured motion data has added increased realism in character animation. In order to make

An outbreak of foot-and-mouth disease caused by serotype O virus occurred in cattle and pigs in South Korea during November 2010–April 2011. The highest rates of case and virus detection were observed 44 days after the first case was detected. Detection rates declined rapidly after culling and completion of a national vaccination program. Foot-and-mouth disease (FMD) is a highly contagious disease caused by foot-and-mouth disease virus (FMDV; family Picornaviridae, genus Aphthovirus). FMDV serotypes O, A, and Asia1 are widespread in Southeast Asia (1). In South Korea, small-scale outbreaks of FMDV infection caused by serotype O occurred in March 2000, May 2002, and April 2010 (2–5), and an outbreak caused by serotype A occurred in January 2010 (6). In contrast, an outbreak during November 2010–April 2011 was much more widespread (7). We reviewed the progression of this outbreak and methods used to control it, including culling and vaccination of pigs and cattle. The Study Clinical signs of FMD in animals appeared on November 23, 2010, in a pig-farming complex in Gyeongbuk Province. Reporting to the central government was delayed for ≈1 week because of misdiagnosis caused by false-negative results from a pen-side antibody kit. FMDpositive test results were confirmed on November 28–29

Communication performance between two processes in their own domains on the same physical machine gets improved but it does not reach our expectation. This paper presents the design and im-plementation of high-performance inter-domain communication mechanism, called XWAY, that maintains binary compatibility for applications written in standard socket interface. As a result of our survey, we found that three overheads mainly contribute to the poor performance; those are TCP/IP processing cost in each domain, page flipping overhead, and long communication path be-tween both sides of a socket. XWAY achieves high performance by bypassing TCP/IP stacks, avoiding page flipping overhead, and providing a direct, accelerated communication path between do-mains in the same machine. Moreover, we introduce the XWAY socket architecture to support full binary compatibility with as lit-tle effort as possible. We implemented our design on Xen 3.0.3-0 with Linux kernel 2.6.16.29, and evaluated basic performance, the speed of file trans-fer, DBT-1 benchmark, and binary compatibility using binary im-age of real socket applications. In our tests, we have proved that XWAY realizes the high performance that is comparable to UNIX domain socket and ensures full binary compatibility. The basic per-formance of XWAY, measured with netperf, shows minimum la-tency of 15.6 µsec and peak bandwidth of 4.7Gbps, which is supe-rior to that of native TCP socket. We have also examined whether several popular applications using TCP socket can be executed on XWAY with their own binary images. Those applications worked perfectly well.
