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.   Quantitative relationship of two viruses (mrnv and xsv) in white-tail disease of macrobrachium rosenbergii 期刊论文  iSwitch采集 Diseases of aquatic organisms, 2006, 卷号: 71, 期号: 1, 页码: 11-17 作者:  Zhang, Huajun;  Wang, Hanmin;  Yuan, Junfa;  Li, Lijuan;  Zhang, Jianhong 收藏  |  浏览/下载：38/0  |  提交时间：2019/05/09 Macrobrachium rosenbergii  Nodavirus  Extra small virus  Real-time rt-pcr  White-tail disease   Real-time accurate hand path tracking and joint trajectory planning for industrial robots(I) 期刊论文  OAI收割 Journal of Central South University of Technology, 2002, 卷号: 9, 期号: 3, 页码: 191-196 作者:  Tan GZ(谭冠政);  Liang F(梁丰);  Wang YC(王越超) 收藏  |  浏览/下载：22/0  |  提交时间：2012/05/29 industrial robots  real time  accurate  hand path tracking  joint trajectory planning  extra knot
