This paper proposes a real-time method for 3D eye performance reconstruction using a single RGBD sensor. Combined with facial surface tracking, our method generates more pleasing facial performance with vivid eye motions. In our method, a novel scheme is proposed to estimate eyeball motions by minimizing the differences between a rendered eyeball and the recorded image. Our method considers and handles...
Nowadays, the microelectronics industry broadly uses the flipchip technology to enhance the packaging density. However, the small size and the unique geometry of the flip-chip solder joints induce the electromigration (EM) reliability issue. In this study, a Pb-free solder joints (SAC1205) was EM tested by a current of 7.5×103 A/cm2. During the tests, a three-dimensional (3D) X-ray laminography method...
Polarimetric Targets Decomposition is to decompose polarimetric data into several components by different physical scattering mechanism. Traditional decomposition methods are model-based, whose basis matrix is fixed to typical physical scatterers, such as surface, double bounce, volume. However, those methods cannot distinguish the differences of two kinds of surface scattering, or two kinds of double...
Using numerical scattering simulation of the BART (bidirectional analytic ray tracing method), an angular sequence of high-resolution 2-D ISAR (inverse synthetic aperture radar) images of a space target is produced. The Kanade-Lucas-Tomasi (KLT) feature tracker is then adopted for extracting feature points and matching all angularly consecutive ISAR images. 3-D positions of those featured points can...
Glioblastoma multiforme (GBM) is the most common and malignant primary brain tumor in adults because of its highly invasive behavior. The existing treatment for GBM, which involves a combination of resection, chemotherapy, and radiotherapy, has a very limited success rate with a median survival rate of <1 year. This is mainly because of the failure of early detection and effective treatment. We...
The traffic scenario consists of the road scenario and traffic elements. The original image sequences can be captured by a moving platform equipped with camera by driving along the road. In this paper, an approach based on augmented reality is proposed that supplements new elements (traffic cones, obstacles, etc.) into those image sequences. We model the traffic scenario in the 3D space of the scene,...
Aiming at control of remote teleoperation for mobile robot using at search and rescue, especially for application in a complex environment, this paper presents a vision-based mobile robot remote control system. After the realization of the physical simulation, transplantation of this system to the mobile self-balancing robot control physical entities also success, giving a callback-style remote control...
This paper presents a method to synthesize a realistic facial animation of a target person, driven by a facial performance video of another person. Different from traditional facial animation approaches, our system takes advantage of an existing facial performance database of the target person, and generates the final video by retrieving frames from the database that have similar expressions to the...
The scene simulation is an important part of virtual reality system. The creation and development of scene simulation provides powerful methods support to the research of forensic science. In this paper, the visual simulation and forensic science was closely integrated; the composition structure and function of OpenGL performer which is advanced development tools on the field of visual simulation...
This empirical study explores the structure of customer individual innovation behavior (CIIB) of Chinese service industry. According to the theory of individual innovation behavior(IIB) and the specific characteristics of customer involved in service innovation, we develop the CIIB scale. Exploratory factor analysis (EFA) of data from a sample of 242 customers shows that CIIB has there dimensions:...
