	A hybrid median filter for enhancing dim small point targets and its fast implementation (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Multimedia and Signal Processing, CMSP 2011, May 14, 2011 - May 15, 2011, Guilin, Guangxi, China Yang Q. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 Weak stars and middle altitude orbit satellites or high altitude orbit satellites are presented as dim point targets in images of astronomical observation. 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.
	Small aircraft CAN bus signal acquisition equipment (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 Chen C.-Q. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 Small aircraft often used RS485 bus. But with the complexity of the small aircraft's subsystems increase and the progress of field bus technology CAN bus systems in small aircraft use more and more widely. How to record real-time flight experiment data on the small aircraft's CAN bus and provide test data for reproducing the process of a small aircraft flying is very important. This paper presents a design method of signal acquisition device it can be used for small aircraft flying field experiment. 2010 IEEE. as the main chip with DSP2812 SJA1000 as CAN controller CTM1050 as the CAN transceiver CF card as storage media. Gives the diagram of its hardware and software design process. Combined with the background of a small aircraft testing the instrument for data acquisition when the ground experiments and flight progress. Experimental data show that the design of high reliability and CAN signals can effectively complete the record
	The research for EO imaging system simulation (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging, ISPDI 2007: Optoelectronic System Design, Manufacturing, and Testings, September 9, 2007 - September 12, 2007, Beijing, China 作者: Wang L.-J.; Zhang X.; Zhang X.; Zhang X.; Zhang J.-P. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 Electric-Optical (EO) imaging systems are modern systems especially the one consists of aspheric optics and image processing called wavefront coding system. The design concept of this kind system is totally different from the traditional image system. The trade-off between the complexity of the image deconvolution and the depth of focus extended should be considered. So we establish a simulation model consisting of optical optimization design system signal-to-noise ratio analysis and recovered image evaluation. The data can be exchanged among them. This simulation tools will be very useful in system design process.
