	The research of digltal CR medicine image adapitive enhancement method (EI CONFERENCE) 会议论文 OAI收割 4th International Conference on Mechanical and Electrical Technology, ICMET 2012, July 24, 2012 - July 26, 2012, Kuala Lumpur, Malaysia Ming-Hui Z.; Yao-Yu Z. 收藏 \| 浏览/下载：65/0 \| 提交时间：2013/03/25 Digital CR medicine radiation image is in doctor's favor and has became medicine imaging technology new hot spot because of its high gray contrast powerful computer disposal function little radiation dosage non-film diagnosis different area consultation. But degradation of digital X-ray medical image such as low contrast and blurring during radiographic imaging caused by complexity of body tissue and effects of X-ray scattering and electrical noise etc. can worsen the results of analysis and diagnosis. So it is usually needed that CR medicine image is enhanced to improve its vision quality and easy to doctor's more accurate diagnosis. The general enhancement algorithms over enhancing the contrast and lose image details aiming at the defects an enhancement algorithm for CR image is proposed based on the ratio of deviation to mean of domain. The arithmetic enhance CR image edge details by adjusting factor K based on the ratio of deviation to mean of domain of CR image. Experiment results demonstrate that the algorithm enhances CR image detail and CR image enhanced has good visual effect the adaptive enhancement method is fit for CR medicine image.

	Design and analysis of Roll-Swing imaging seeker scan scheme (EI CONFERENCE) 会议论文 OAI收割 2010 2nd International Conference on Industrial Mechatronics and Automation, ICIMA 2010, May 30, 2010 - May 31, 2010, Wuhan, China Bai Y.; Liu B.; Jia H.; Guo L. 收藏 \| 浏览/下载：25/0 \| 提交时间：2013/03/25 To achieve an optimum scan area and target stay time for Roll-Swing imaging seeker the scanning process is analyzed. The method of ground imaging area calculation is proposed in this paper. A kind of Roll-Swing imaging frame mechanism is introduced. The flight process simulation base on real flight data is realized. According to imaging sensor parameters and flight data a new scan scheme method is proposed and a new scan scheme is designed. The new scan scheme is compared to traditional scan scheme from different guide lines. The test results indicate that the new scan scheme satisfy requirement of the real flight experiment. 2010 IEEE.
	Animated models coarsening with local area distortion and deformation degree control (EI CONFERENCE) 会议论文 OAI收割 International Conference on Image Processing and Pattern Recognition in Industrial Engineering, August 7, 2010 - August 8, 2010, Xi'an, China 作者: Zhang S.; Zhao J. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 In computer graphics applications mesh coarsening is an important technique to alleviate the workload of visualization processing. Compared to the extensive works on static model approximation very little attentions have been paid to animated models. In this paper we propose a new method to approximate animated models with local area distortion and deformation degree control. Our method uses an improved quadric error metric guided by a local area distortion measurement as a basic hierarchy. Also we define a deformation degree parameter to be embedded into the aggregated quadric errors so areas with large deformation during the animation can be successfully preserved. Finally a mesh optimization process is proposed to further reduce the geometric distortion for each frame. Our approach is fast easy to implement and as a result good quality dynamic approximations with well-preserved sharp features can be generated at any given frame. 2010 SPIE.
	A dynamic data mining model for engineering management (EI CONFERENCE) 会议论文 OAI收割 2009 Second ISECS International Colloquium on Computing, Communication, Control, and Management, CCCM 2009, August 8, 2009 - August 9, 2009, Sanya, China Zhu J.-W.; Tang Y.-G. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 Data mining has become increasingly critical for the success of companies in this emerging era of Engineering Management. As Engineering Management activities increasingly shift to the web the challenge facing corporate management is maintaining competitive advantage by building strong relations with employees customers and suppliers and partners. A good data mining strategy can help achieve this goal. Unfortunately many companies use data mining technologies that do not suit today's new information era. This paper addresses the definitions about data mining area of data mining development of data mining then provide an summary of the driving and impeding forces that help and hinder proper deployment of data mining strategies in Engineering Management. Finally the paper advocates the strategy of data mining for Engineering Management. 2009 IEEE.
