PD solves the Zernike coefficients of the wavefront by utilizing two images obtained with different defocus value. In this paper  we propose a method to restore the image and estimate the wavefront error of an imaging system. And we use present white noises to verify the robustness of the algorithm. We design an experiment system and implement it in our laboratory. The proposed algorithm is validated by computer simulations and experimental results. To use a broadband white object in experimental system a reasonable simplification for the system model is done. Our results show that the robustness against Gaussian white noises of the method is better then the case when the variance value is 0.03. The proposed method can be used as a wavefront sensor and restore the degradative images by photoelectric image system. 2010 SPIE.   An improved discrete particle swarm optimization algorithm for TSP (EI CONFERENCE) 会议论文  OAI收割 2007 IEEE/WIC/ACM International Conference on Web Intelligence and Intelligent Agent Technology - Workshops, WI-IAT Workshops 2007, November 2, 2007 - November 5, 2007, Silicon Valley, CA, United states 作者:  Wang Y.;  Wang Y.;  Wang Y.;  Wang Y.;  Wang Y. 收藏  |  浏览/下载：34/0  |  提交时间：2013/03/25 An Improved discrete particle swarm optimization (DPSO)-based algorithm for the traveling salesman problem (TSP) is proposed. In order to overcome the problem of premature convergence  a novel depressor is proposed and a diversity measure to control the swarm is also introduced which can be used to switch between the attractor and depressor. The proposed algorithm has been applied to a set of benchmark problems and compared with the existing algorithms for solving TSP using swarm intelligence. The results show that it can prevent premature convergence to a high degree  but still keeps a rapid convergence like the basic DPSO. 2007 IEEE.   Studies on information clustering algorithm based on MID 期刊论文  OAI收割 CHINESE JOURNAL OF ELECTRONICS, 2006, 卷号: 15, 期号: 4A, 页码: 918-920 作者:  Ding Shifei;  Shi Zhongzhi   |  收藏  |  浏览/下载：25/0  |  提交时间：2019/12/16 information theory  measure of diversity  information clustering algorithm  measure of increment of diversity  data processing
