Early researches show that the nano filler dispersion has a significant effect on the dielectric properties of resulting epoxy nanocomposites. In this paper a comparative study on the dielectric permittivity, AC breakdown behaviours and glass transition temperature of epoxy nanocomposites loaded with both treated and untreated nano SiO2 fillers has been(More)
Microsoft Kinect camera and its skeletal tracking capabilities have been embraced by many researchers and commercial developers in various applications of real-time human movement analysis. In this paper, we evaluate the accuracy of the human kinematic motion data in the first and second generation of the Kinect system, and compare the results with an(More)
In this paper, we propose a method for temporal segmentation of human repetitive actions based on frequency analysis of kinematic parameters, zero-velocity crossing detection, and adaptive k-means clustering. Since the human motion data may be captured with different modalities which have different temporal sampling rate and accuracy (e.g., optical motion(More)
As the emerging multimedia on the latest social multimedia network, high dimensional video (HDV) data distribution is one of the most challenging problems in social multimedia applications. In the paper, we provide a state-of-the-art analysis on the streaming and interactive technologies for the two most popular representations of HDV, video plus depth map(More)
In this paper, a texture-space geometry partitioning approach is proposed to reduce the computational complexity of searching for geometry partitions for video coding. Additionally, for systems that capture both video and depth data, an enhanced geometry partitioning approach using both texture and depth information is proposed to further improve the(More)
In 3D video coding, to provide the high-quality interactive viewpoint video to audience, it is necessary to jointly optimize coding efficiency of color and depth images at a given bit-rates. In this paper, a region based distortion model is proposed to precisely estimate the error of synthesized virtual view. Furthermore, combined with the rate-distortion(More)
Vision field describes the real world visual information by summarizing the seven-dimensional plenoptic function into three domains: view, light, time, from which a better understanding of previous 3D capture and reconstruction systems can be provided. In this paper, we first show how to reconstruct 3D spatial information from all the three attributes of(More)
