Aiming at overcoming the defects of basic lighting color rendering for LED stage lighting, this paper establishes a new mixing light method with RGBW four-color mixing model. Compared with traditional tricolor light mixing model, it uses the mixing light of white as the fourth input, with the threebasic color of red, green and blue to obtain a new mixing method. Then the original coefficients of RGBW are optimized after adjusting the two parameters of relative spectral power distribution and illuminance of mixing light for locus fitting of blackbody. Finally, better color rendering of white light can be acquired. By the MATLAB simulation and field testing, experimental results have shown that the proposed method will achieve ideal LED lighting performance, which is convenient for color management of lighting control system in modern theatre. © 2017 IEEE.

Depth maps obtained by RGB-D cameras such as ZED are noisy, and there are invalid areas where depth values absent in the maps, which will affect the subsequent improved processing. This paper investigates the restoration and optimization of degraded depth image method based on RGBD data captured by ZED by means of selective filtering and conditional auto-regressive model with edge constraints. Firstly, we divide invalid areas into two categories, including the internal invalid areas caused by reflection and invalid edge caused by occlusion. Then, we use corresponding median filter and mean filter in the different selective areas to obtain the initial restored depth map with no empty area. The edges of objects contain massive information, therefore, an adaptive auto-regressive (AR) model is used to further optimize the depth of the edge area. Additionally, we add the edge information to the sampled image to maintain local detail. Experiments show that with the proposed method we can recover the depth data with high accuracy and effectiveness. © 2017 IEEE.

By taking both CMF (Common Mode Failure) and middle states into account, numerical analysis of availability of cluster system is analyzed. Firstly, a CTMC (Continuous Time Markov Chain) model of cluster system containing three cluster nodes is constructed with failure rate (λ), repair rate (μ), CMF rate (γ), reconfiguration rate (β) and reset rate (δ) etc. Then the steady state solution of the CMTC model is concerned by solving the equations with the combination of several parameters. Subsequently, the effect of probability of being in automatic recovery mode (k) on availability of cluster system is analyzed and discussed via numerical values-based chart thereby. This work offers quantitative analysis of cluster system's availability.

AIP Conference Proceedings 2018年第1期2036卷

作者： Zhibin Su Bing Liu Jingyu Liu Hui Ren Fakong Wei 1Key Laboratory of Acoustic Visual Technology and Intelligent Control System Ministry of Culture and Tourism Communication University of China Beijing China 2Lanzhou University of Technology of Stage Equipment Institute China

To protect the acoustical environment of auditorium in performing place, this paper mainly focusses on the emission noise measurement method of stage machinery. For the high noise and frequently-used equipment during the performance, the measurement equipment, environment and condition, detection position, evaluation parameter, tested object and the running requirement are all studied and discussed. In particular, the suitable test point and load demand is analyzed through the simulation of EASE software and the noise measurement under laboratory environment. Our research aims to provide the basic work for developing the draft standard for stage machinery noise, which has certain application value to improve the audio-visual effects and control the noise pollution for modern theatre.

The paper presents a limit analysis of psychophyslcal methods which is designed for the changes in visual perception of when visual stimulus appear alternately. The purpose of this experiment is to reveal the quantizing relationship between stimulate and feeling response. Meanwhile, we studied the perception of image on visual information considering the color psychological attributes to clarify the changes of visual perception when image information presented by limit analysis approach. Based on the psychological scale, the test images were divided into three types using psychophyslcal analysis. The test results of psychophyslcal methods also were validated, focusing the verifications on the correctness of the main image date behind the limit analysis. The images data is derived from entropy, moment of inertia, local balance, and correlation. Both the two kinds of analysis arrived at the same conclusion, which turned out that the image perception happens in emotional process and depends upon the psychophyslcal property and signal superposition response.

Network music is an important form that people listen to music now, in PC desktop system, browser with HTML5 and the multimedia plugin can imply very good online selection ways and listen to the program with beautify pages, but in the set-top box system, it is extremely different. In this paper, we use a network set-top box with embedded browser system to realize an asynchronous access mode of music website design, the system uses the JSE to achieve music file playback controls, at the same time, the online transcoding system, on the server side for transcoding to improve on the different types of music file playback compatibility, and with an asynchronous access pattern method, time-consuming part is transferred into the background, and the browser Ajax method for interactive prompting. The experimental results show that the system has better interactive performance with respect to the normal music website which is usually synchronized visit ways, and improve the user's listening and viewing experience.
