A light-weighted and electrically large-sized multi-beam cylindrical dielectric lens antenna is presented in this paper. The lens antenna is fed by an arc array with 10 E-shaped patch antennas. The cylindrical lens is made of foam plastics with a dielectric constant of 1.1, and composed of three layers. A lot of holes are loaded in each layer of the foam plastics, and the holes are filled with nylon with a dielectric constant of 5.5. Simulation results show that the antenna can produce 10 narrow beams and the crossover of two adjacent beams occurs at the -3-dB level. The beams cover a wide scan angle of 120° in the azimuth range and the 3-dB beamwidth in the elevation plane is more than 70°.

This paper describes a new approach aimed at automatic identify events of abandoned and stolen objects detection in video surveillance system. Our method mainly include three steps of data processing: the first processing phrase is object extraction, involving a background subtraction algorithm which dynamically updates two sets of background. Then, extracted objects are classified as static or dynamic objects. Finally, a decision-making model is employed to calculate a confidence score for the classification about event, and an alarm will be automatically triggered if the score of corresponding action is higher than a pre-defined threshold. Also, Compared with the existing detection algorithm, the robustness and efficiency of the method was tested on our real time video surveillance system and evaluated by public database such as AVSS 2007 data sets.

Dual-mode cavity filters have been widely used in wireless communications systems due to their advantages of small size, low loss and high power handling capability. In this paper, a novel dual-mode coaxial bandpass filter with stepped impedance resonator (SIR) configuration is proposed. The resonator that supports the TEM mode can exhibit two resonances. By combining multiple resonators, higher order filters with narrowband response can be realized within compact structure. Besides, a 4th order filter is designed, theoretical analysis and simulation results prove the fesibility of the proposed class of filters.

The proposed microstrip line based approach for electromagnetic band-gap (EBG) investigation defines the band-gap through the detection of the resonant frequencies of fsh and fse, while conventional approaches of dispersion diagram calculation model, TEM waveguide model, and suspended microstrip line model directly show the band-gap. The proposed approach is based on composite right/left handed (CRLH) and zeroth-order resonator (ZOR) theories, then, the resonant frequencies fsh and fse of EBG structure can be detected by our designed microstrip line based approach. Thereafter, the band-gap of an EBG structure surface is defined as it is delimited by the two resonant frequencies. Compared to the conventional approaches, our proposed approach has many advantages, such as computer resources and time-alleviated, fast prediction of the resonant frequencies and band-gap, and easy of construction and directly measurement. The approach is validity by full wave simulations.

In the stereoscopic image quality assessment, the overwhelming majority of previous studies convert color images to gray scale images, which loses the color information in order to reduce the complexity. However, the loss of color information is not conducive for color stereoscopic images to make the right assessment. To solve this problem, saturation quality assessment model of stereoscopic image base on Gaussian white noise was proposed. Firstly, extract saturation gradient values of eight directions around each pixel from reference images and distorted images. Secondly, euclidean distance of eight gradient feature vectors are calculated between gradient values of reference image and gradient values of distorted image. Euclidean distance are taken as image quality evaluation indexes. Thirdly, using curve model for fitting the mapping relationship that between indexes and DMOS. Finally, eight directions of indexes are used to multiple linear regression analysis and the regression equation is saturation quality assessment model of stereoscopic image. The method was tested on the LIVE 3D Image Quality Database published by university of Texas. The Linear Correlation Coefficient (LCC) and Spearman Rank Order Correlation Coefficient (SROCC) achieved 0.917 and 0.918.The results have high accordance with the subjective evaluation.
