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.

In the system  In the course of detecting  push-broom movement of the satellite is simulated through using double supporting U structure precision rotary platform with remote sensor by angular speed 0.555/s  regard Nyquist frequency target as detecting aim  within the range of 5 and control precision on steady speed achieves 0.3%  in order to solve matching uncertainty between the CCD pixel and the vertical target strip image when the remote sensor does push-broom  make matching simplify  enhance the measurement result the accuracy. So the tolerance a/n arithmetic progression gap target strip is joined in each group of rectangular vertical group target strip. The remote sensor obtains in vertical  the level and 45 the direction 0 fields of view  0.86 the field of view Nyquist frequency target strip image after detected  a group target strip which can precision matching to TDICCD pixel at least can be obtained through analysis and dealing with 0.86 field of view's target strip image. The experiment not only verifies the detecting system's feasibility but simultaneously verifies whether to have the high quality dynamic imaging quality when TDICCD push-broom technology is adopted on the remote sensor developed. 2010 Copyright SPIE - The International Society for Optical Engineering.   有效的海上运动目标检测方法 期刊论文 2009 谢小竹; 洪景新; 肖思兴 收藏  |  浏览/下载：4/0  |  提交时间：2016/05/17 成像特性  Sobel算子  感兴趣区域  中心点  imaging characteristic  sobel arithmetic operators  regions of interest  center   A general axiomatic system for image resolution quantification 其他 2006-01-01 Jiang, M; Wang, G; Ma, XM 收藏  |  浏览/下载：1/0  |  提交时间：2015/11/10 imaging system  point spread function (PSF)  image resolution  arithmetic mean  geometric mean  POINT SPREAD FUNCTION  SPIRAL CT IMAGES  COMPUTED-TOMOGRAPHY  RESTORATION  NOISE   Application of SRTM-DEM based two-pass SAR interferometry for detecting seismic deformation on high-altitude rugged terrain - A case study in Kokoxili Ms8.1 earthquake, 2001 会议论文 2005 IEEE International Geoscience and Remote Sensing Symposium, IGARSS 2005,, Seoul, Korea, Republic of, July 25, 2005 - July 29,2005 Zhang, Yanmei; Cheng, Xiao 收藏  |  浏览/下载：11/0  |  提交时间：2014/12/07 Earthquakes  Digital arithmetic  Interferometry  Landforms  Radar imaging  Seismology  Synthetic aperture radar
