However the general enhancement algorithms over enhance the contrast and noise  due to image details lost  aiming at the defects  a mammary gland CR medicine image adaptive enhancement arithmetic based on image gray entropy is put forward. The arithmetic adapts dizzy image to magnify selected spatial frequency response in order to enhance the edge details of mammary gland CR images. It can adjust weighted factor K according to image gray characteristics namely pixel gray entropy. Experiments results demonstrate that mammary gland CR image enhanced by the algorithm has abundant details and high signal-to-noise ratio  moreover  CR image enhanced has good visual effect. So the method is effective and fit for enhancing CR medical radiation image edge details. 2012 IEEE.   an approximate approach to belief revision 期刊论文  OAI收割 LOGIC JOURNAL OF THE IGPL, 2012, 卷号: 20, 期号: 2, 页码: 486-496 Luan Shangmin; Dai Guozhong; Magnani Lorenzo   |  收藏  |  浏览/下载：22/0  |  提交时间：2013/09/17 Belief revision  approximate algorithm  integrity constraints  finite belief base   Study on image real-time interpretation based on particle filter (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China 作者:  Liu S.-J. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 In order to satisfy to the real-time requirement of image interpretation system in photoelectric measurement equipments  a kind of hardware acceleration system with MIMD distributed multi-processor architecture based on SOPC technology is designed. The particle filter algorithm is proposed to process image interpretation for state estimation problem of nonlinear and non-Gaussian system. This algorithm does not involve conventional linearization transform  and has approximated the posterior probability density by a set of discrete particles. Therefore the approximate optimum result is educed. It has a high accuracy and a rapid convergence. Experimental results show that the algorithm be adequate to real time  accuracy and robustness  meets the requirement of image interpretation and possesses practical significance for engineering applications. 2011 IEEE.   近似骨架导向的归约聚类算法 期刊论文  OAI收割 电子与信息学报, 2009, 卷号: 31, 期号: 12, 页码: 2953-2957 宗瑜; 李明楚; 江贺 收藏  |  浏览/下载：24/0  |  提交时间：2011/03/18 聚类问题  NP-难解  启发式算法  近似骨架  Clustering issue  NP-hard  Heuristic algorithm  Approximate backbone  骨架导向  归约  聚类算法  optimal solutions  近似骨架  search space  局部最优解  clustering algorithm  Reduction Algorithm  聚类问题  high quality  算法收敛速度  数据集  研究成果  搜索空间  实验结果  聚类质量  基本思想  骨架特征  multipleCluster analysis  Computational complexity  Feature extraction  Heuristic algorithms  Heuristic methods  Optimal systems   A method for matching Chinese place-name data 会议论文  OAI收割 Proceedings of SPIE Yilan L.; Jinfeng W. 收藏  |  浏览/下载：24/0  |  提交时间：2012/06/30 Place-name  cartology  edit distance  Chinese  approximate string  matching  bit-parallelism  filtering  BPM  BPM-BM  SQL commands  algorithm   HilbertChord: A Kind of Method for Managing Service Resources in P2P 期刊论文  OAI收割 Microcomputer Information., 2009, 卷号: 25, 期号: 15, 页码: 107-108,52 作者:  SHAO Yichuan;  SHEN Derong;  ZHAO Hongwei   |  收藏  |  浏览/下载：16/0  |  提交时间：2021/02/26 P2P  Chord algorithm  Hilbert curve  grid service  approximate query   最小包含球算法及其在支持向量机中应用的研究 学位论文  OAI收割 工学博士, 中国科学院自动化研究所: 中国科学院研究生院, 2008 作者:  王永庆 收藏  |  浏览/下载：71/0  |  提交时间：2015/09/02 支持向量机  最小包含球  凸二次规划  近似算法  对偶理论  Support Vector Machine  Minimum Enclosing Ball  convex quadratic programming  approximate algorithm  duality theory
