However images of different band channels obtained at the same time didn't coincide as there were spaces between lines. Pixel numbers to be adjusted between images of different channels varied when the space camera worked by swaying forward and backward or adjusted row transfer period to compensate image movement. An automatic multispectral images synthesis algorithm of space camera was put forward on the basis of analysis of such phenomenon. In this algorithm a new evaluation function was used to determine pixel numbers to be adjusted and the image regions of each band channel to be clipped. In this way images of different band channels could be synthesized automatically to obtain an accurate colorful image. This algorithm can be used to dispose a large mount of images from space camera directly without any manual disposal so that efficiency could be improved remarkably. In validation experiments the automatic multispectral images synthesis algorithm was applied in synthesis of images obtained from outside scene experiment of a multispectral space camera. Result of validation experiments proved that the automatic multispectral images synthesis algorithm can realize accurate multispectral images synthesis of space camera and the efficiency can be improved markedly. 2010 SPIE.   Fast covariance matching based on Genetic Algorithm (EI CONFERENCE) 会议论文  OAI收割 2010 6th International Conference on Wireless Communications, Networking and Mobile Computing, WiCOM 2010, September 23, 2010 - September 25, 2010, Chengdu, China 作者:  Zhang X.;  Zhang L.;  Zhang L.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 This paper proposes an effective framework to boost the efficiency of covariance matching. In this framework  covariance matrices are used to match object in complex environment by fusing multiple features. Then  Genetic Algorithm (GA) is employed to improve the processing speed of covariance matching. To take advantage of the property of GA for the optimization in large search spaces to covariance matching  a fitness function is designed using the distances between the covariance matrices of model and candidate regions. Experimental results show that the proposed approach can improve the processing speed of covariance matching observably. The computing speed of the proposed method is at least 7 times than that of exhaustive searching. 2010 IEEE.   Interleukin-6, desmosome and tight junction protein expression levels in reflux esophagitis-affected mucosa 期刊论文  OAI收割 WORLD JOURNAL OF GASTROENTEROLOGY, 2009, 卷号: 15, 期号: 29, 页码: 3621-3630 作者:  Li FeiYue;  Li Yan   |  收藏  |  浏览/下载：24/0  |  提交时间：2021/02/03 DILATED INTERCELLULAR SPACES  BARRIER FUNCTION  OCCLUDIN  PERMEABILITY  ZO-1  LOCALIZATION  INTERACTS  DISEASE  MODEL  Reflux esophagitis  Desmosome  Tight junction  Proteins  Mucosa   Randomization of Q(p) spaces on the unit ball of C-n 期刊论文  OAI收割 SCIENCE IN CHINA SERIES A-MATHEMATICS, 2005, 卷号: 48, 页码: 306-317 作者:  Li, B;  Ouyang, CH 收藏  |  浏览/下载：34/0  |  提交时间：2015/07/17 random power series  function spaces  the unit ball   MARTINGALE TRANSFORMS WITH UNBOUNDED MULTIPLIERS 期刊论文  OAI收割 PROCEEDINGS OF THE AMERICAN MATHEMATICAL SOCIETY, 1992, 卷号: 114, 期号: 3, 页码: 831-838 作者:  CHAO, JA;  LONG, RL   |  收藏  |  浏览/下载：24/0  |  提交时间：2018/07/30 MARTINGALE TRANSFORM  HARDY SPACES  MAXIMAL FUNCTION  SQUARE FUNCTIONS  BMO  EXTRAPOLATION
