Correlation filters present the composite properties which have been successively used in target detection. Particle filter are combined to locate the targets in real-time. Our contribution is proposing a general algorithm that is able to detect and track pedestrians in clutter environments. We also create a different view pedestrian dataset. Experiments show our algorithm is comparative when there is block and occlusion in tracking. 2011 IEEE.   DOA estimation algorithm of UWB signal based on unitary circuit array (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者:  Zhang X.;  Chen X.;  Chen X.;  Chen X. 收藏  |  浏览/下载：31/0  |  提交时间：2013/03/25 In this contribution  unitary circular array (UCA) techniques for estimating Direction of Arrival (DOA) of Ultra wideband (UWB) propagation signals are studied. Aiming at the defects of the DOA algorithms under uniform linear array (ULA) only can estimate 180 degree unfaintness angles  in this paper  the algorithms of one-dimensional and two-dimensional DOA estimation for UWB signals based on unitary circular array (UCA) are proposed. In order to estimate DS-UWB signals within 360 degree angles  the UCA-CSM-RB-MUSIC algorithm is proposed  which can estimate 360 degree unfaintness azimuth angles. 2010 IEEE.   Research on the close noise field of the piezoelectric pump (EI CONFERENCE) 会议论文  OAI收割 2006 IEEE International Conference on Mechatronics and Automation, ICMA 2006, June 25, 2006 - June 28, 2006, Luoyang, China Jizhuang L.; Jianhui Z.; Shouyin W.; Qixiao X.; Desheng L. 收藏  |  浏览/下载：50/0  |  提交时间：2013/03/25 Restraining the noise  meanwhile  improving the dynamic characteristics of the driving power of piezoelectric pump effectively are the final purposes of doing research on the reciprocating and flexural vibration of the piezoelectric vibrator. However  among many papers regarding piezoelectric pump  there are very few papers about the research on the noise of piezoelectric pump. This is far less than the research on the application of the piezoelectric pump in other fields. In this paper  the research on the flexural vibration deformation and vibration radiation noise of the piezoelectric vibrator are carried out. Firstly  the vibration equations of the piezoelectric vibrator are built and flexural vibration deformation function is deduced. Then  the simplified vibration model of the piezoelectric vibrator is introduced by using vibration theories of micro-area piston. Furthermore  theoretical calculation equations of sound pressure in close noise field and noise contribution equation of fluid in pump are deduced. Finally  a comparison is made between the theoretical calculation value and experimental value  and the contribution quantities of the piezoelectric vibrator and fluid in pump are obtained respectively under different frequencies. The consequence approves that the theory introduced by this research is true. 2006 IEEE.
