At first, the authors propose an adjacent pixel gray order-preserving principle. Adjacent pixel gray order-preserving principle is the basement of local enhancement method which ensures that there is no distortion in processed image. And then, the authors propose an iterative algorithm, which could stretch gray-scale difference of adjacent pixels in premise of not changing gray magnitude relationship between adjacent pixels. At last, the authors propose a totally reference image quality assessment method based on adjacent pixel gray order-preserving principle. According to this quality assessment method, the authors made a set of comparative experiments with local histogram equalization and method. Experimental results show that the proposed enhancement method can get higher score and provide better visual effects, fully demonstrating its effectiveness. According to this quality assessment method, the proposed method shows a good effectiveness, through experimental results and comparison with local histogram equalization method.   Improved method of target detection on optoelectronic hybrid joint transform correlator in cluttered scences (EI CONFERENCE) 会议论文  OAI收割 2011 3rd International Conference on Mechanical and Electronics Engineering, ICMEE 2011, September 23, 2011 - September 25, 2011, Hefei, China 作者:  Yang L.;  Yang L. 收藏  |  浏览/下载：24/0  |  提交时间：2013/03/25 A classical joint transform correlator (JTC) usually yields large correlation sidelobes as well as a large correlation peak width  strong zero-order peak  and low diffraction efficiency  which make the detection ability of JTC lower. To overcome these difficulties  firstly  a joint power spectrum (JPS) subtraction technique in Fourier plane was proposed  where reference image power spectrum and object image power spectrum are subtracted from the JPS before inverse Fourier-transform operation  it is obvious that the modified JPS removes the zero-order term. Secondly  a fringe-adjusted filter (FAF) was presented to suppress sidelobes and noises. The modified JPS is multiplied by a FAF before the inverse Fourier-transform operation to obtain the cross-correlation peak. Computer simulations demonstrated the improved method can obviously remove zero-order diffraction and effectively suppress the sidelobes and noises compared with classic JTC  and then improve the detection ability for JTC. Experimental results presented the sharp correlation peak and also confirmed the method effectiveness.

For this question  this paper introduces the interval number and grey decision making principle and bring forward a combat effectiveness evaluation model based on the interval number and grey decision making. Combined with the case to analyze  this paper verifies the reasonableness of the model. The results show that this model can truly reflect the comprehensive evaluation value of the weapon equipment combat effectiveness. 2011 IEEE.   Analytical and Numerical Study on the Uniformity of Temperature Difference Field in Heat Exchangers* 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 1995, 卷号: 4, 期号: 2, 页码: 104,108 Zhi-Xin Li; Da-Xi Xiong; Sen-Quan Zhou 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/13 heat exchanger  uniformity of TDF  effectiveness.   Analytical and Numerical Study on the Uniformity of Temperature Difference Field in Heat Exchangers* 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 1995, 卷号: 4, 期号: 2, 页码: 104,108 作者:  Zhi-Xin Li;  Da-Xi Xiong;  Sen-Quan Zhou   |  收藏  |  浏览/下载：20/0  |  提交时间：2013/03/13 Heat Exchanger  Uniformity Of Tdf  Effectiveness.
