3D-HEVC is the latest 3D video project of MPEG for 3D video coding. To compress the depth videos in 3D-HEVC efficiently, depth distortion models considering the distortions in synthesized views have been introduced. However, these models introduce a big burden in coding complexity. In this paper, a configuration of depth distortion models applied at each encoding decision stage of 3D-HEVC is proposed...
Residual stress has significant impacts on the performance of the pipe components, especially on its strength, fatigue life and corrosion resistance and dimensional stability. It has been a difficulty and hot issue that how to evaluate the residual stress status of the surface or a certain depth of tube components quickly, non-destructively and accurately. Based on acoustoelasticsticity theory, the...
In this paper, a low power parallel surveillance video encoding system based on joint power-speed scheduling is proposed. The relative relationships among the CPU statuses, total power consumption and encoding speed are analyzed and modeled for multi-core processors. Based on the power directional graph and the relative encoding speed model, the working statuses of the cores are controlled jointly...
In surveillance systems, low bit rate video coding is necessary to reduce the storage and bandwidth consumption, especially for high definition video coding. In [1], we proposed an adaptive coding method to code the active regions with traditional slices and background with the proposed S slice respectively. The S slice contains less syntax elements than the conventional P slice. This paper further...
As a state-of-the-art video compression technique, H.264/AVC has been deployed in many surveillance cameras to improve the compression efficiency. However, it induces very high coding complexity, and thus high power consumption. In this paper, an early skip mode decision algorithm is proposed to reduce the computational complexity and power consumption in surveillance video compression by detecting...
Video surveillance has been widely applied in broad area to improve the public safety and to protect the residential privacy. Because of the requirements in storing the video data over a period of time for future use and because of the huge size of the raw video data, video compression technique has been integrated into the video camera of the surveillance system. As a state-of-the-art video compression...
Because of the fast growth of Web application and relative technology, the automatic testing for Web has become more and more complexity. This paper proposed an automatic system for Web-app functional testing which based on a XML description and also integrated the web pagespsila structure analysis. It improved the traditional way of record, and it can auto-generate test data and test cases by the...
