They have low intensity and occupy few pixels in image. In most situations  the background of sky is always ununiform and there exists pulse noises. Thus results in targets submerging in background noises and low signal noise ratio (SNR). Median filter is an effective method for removing pulse noise. But it can blur image after modifying gray of non-noise pixels when image has low SNR. A hybrid median filter algorithm is proposed to process low SNR dim point targets image. The newly proposed method can suppress the pulse noises  also can increase target $SNR$ and does not add extra fake targets. The time complexity of median filter is O(N2)(N is the widow size) and is difficult to implement in hardware. For quasi real time application  a fast implementation of our hybrid median filter is proposed to reduce the time complexity to O(N). Experimental results show that the newly proposed algorithm is superior to ordinary median filter and fast median filter by comparing visual effect and performance. 2011 IEEE.   Synthesis and luminescence properties of Eu3+-doped silicate nanomaterial (EI CONFERENCE) 会议论文  OAI收割 17th International Conference on Dynamical Processes in Excited States of Solids, DPC'10, June 20, 2010 - June 25, 2010, Argonne, IL, United states 作者:  Zhang J. 收藏  |  浏览/下载：29/0  |  提交时间：2013/03/25 In this paper  we introduce a sol-gel process for preparing Y 2Si2O7: Eu3+ nanocrystals. The rare earth compounds were dispersed in the SiO2 colloids and the monodisperse nano-scale composite materials were prepared. The reactant mass fraction and heat treatment temperatures could affect the structures and emission spectrum properties of as-synthesized samples. The samples emit the strong red light upon excitation under the ultraviolet. The main peaks originate from 5D0-7F2 electric dipole transition of Eu3+. With regard to the samples treated at different temperatures  the emission spectra obtained under 266 nm excitation show different shapes of spectra lines and relative intensities  indicating that the Eu3+ ions have been located in different local environments. 2011 Published by Elsevier B.V.   Comparative Study on Preparation and in vitro/in vivo Release Behavior of Huperzine A Biodegradable Sustained-release Microspheres for Injection 期刊论文  OAI收割 Chinese Journal of Pharmaceuticals, 2009, 卷号: 40, 期号: 6, 页码: 421-424 作者:  PAN Feng;  CHEN Qing-hua;  BAO Yong-chu;  ZHU Da-yuan;  JIANG Shan-hao   |  收藏  |  浏览/下载：23/0  |  提交时间：2019/01/08 huperzine A  microsphere  burst effect  o/w emulsion in-liquid drying process  o/o emulsion in-liquid drying process   Mechanisms of energy transfer in Pr3+ and Cr3+ codoped SrAl12O19 phosphor (EI CONFERENCE) 会议论文  OAI收割 209th ECS Meeting, May 7, 2006 - May 12, 2006, Denver, CO, United states 作者:  Zhang J.;  Wang X.-J.;  Zhang G.;  Zhang G.;  Zhang G. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 A two-step energy transfer was observed in Pr3+ and Cr 3+ codoped SrAl12O19 phosphor  which results in a two-photon luminescence for one UV/vacuum-UV photon absorbed. For one Pr 3+ ion excited to the lowest 4f5d states  two Cr3+ ions may be excited and emit two red photons due to 2E- 4A2 transitions of the Cr3+ ions  Cr 3+ ions can be excited into the 4T1(F) levels by cross relaxation of Pr3+ 1S0- 1I6 or by direct energy transfer from Pr3+ 3P0  1 states. The mechanisms of the two-step energy transfer process were studied based on spectra and lifetime measurements. copyright The Electrochemical Society.
