"The extragalactic background is very faint, and it is easily confused with the bright emission from the Milky Way," says Ackermann. With the background isolated in their studies (these background measurements are published in the 12 March edition of the journal Physical Review Letters ), Ajello and Ackermann then began to compare it with observations of relatively nearby active galaxies with black holes (called active galactic nuclei, or AGN).

系外伽玛射线背景是非常微弱的，而且很容易受到系内辐射源的干扰，（ Ackermann 等人对背景值的测量公布于3月12日的《物理评论快报》上）， Ajello 和 Ackermann 同时将这个测量结果与附近已被观测过的相对活跃的星系黑洞参数进行比较，这些参照对象有个专有名词，称为活动星系核， AGN 。

There is a brief introduction about the development of western just view in Chapter one, among them it is a key about understanding of the social just concept and value judgment, which create the academic background for the just dispute of Rolls and Nozick, promise that will explain next at the same time; Chapter two in this text should explain emphatically, through the two theory frame exposition and comparative analysis, we can draw the conclusion that the essential of the dispute focuses on the value judgment of social justice, that is to say , it is the understanding to right " question ; It is the investigation of social background aboutthe dispute mainly in Chapter three, this shows , the thinking essences of any social justice are all demanded by the reform to the unreasonable social current situations , and this kind of reform often needs implementing to the system or system aspect, therefore the thinking to the theory needs putting in the specific social environment, only through this can we make the accurate judgment ; Begin from chapter four, it is the practical problem that the full text needs solved, namely the unjust problem existing in the transitional country. By probing into the reference meaning of just ideas between Roils and Nozick, and build up foreshadowing for the system of the last chapter; The last chapter, the corresponding solution has be put forward aimed at the origin of the unjust phenomenon that our society make the transition, namely under the background of system innovation, we should structure the scientific management mode, and realize from "good policy " to the basic " good at managing .

第一章简要的介绍了西方正义观的演变过程，其中关于社会正义概念的理解和价值判断是个关键，同时也是为接下来要阐述的罗尔斯、诺齐克正义观的争论创设一个理论的背景；第二章是本文要着重阐述的环节，通过对两者理论框架的阐述和比较分析，得出两者争论的根本还是社会正义的价值判断上，也就是对于&权利&问题的理解；第三章的设置主要对两者争论的社会背景的考察，由此可以看出，任何社会正义的思考实质都是对不合理的社会现状的改革诉求，而这种改革往往需要落实到体制或制度层面，因而对于理论的思考也需要放在特定的社会环境中，才能做出准确的判断；从第四章开始，是全文需要解决的实际问题，即针对转型国家在转型中存在的非正义问题，探讨罗尔斯、诺齐克正义理念的借鉴意义，并为最后一章的制度架构做铺垫；全文最后一章，针对我国社会转型中的非正义现象的产生根源，提出了相应的解决办法，亦即在制度创新的背景下，构建科学管理模式，实现从&善政&到&善治&的根本转变。

Gaussian background modeling and effective video image foreground and background processing, you want to help!

详细说明：高斯背景建模，有效地对视频图像进行前景和背景的处理，希望对大家有帮助！

The data of the background moving can be obtained by template matching using obvious features of the background and transmitted to difference image sequence processing part.

利用背景中特征较为明显的区域进行模板匹配，得到背景的运动数据，依据此数据将相邻帧图像错位相减。

But an initial background position needs to be set along with the background image you want to use for the effect.

但背景的初始位置需要与背景图一同设置，背景图是用来做效果用的。

In the proposed method,properly spaced background sample pixels are automatically picked up from the image,and then they are used in polynomial fitting for obtaining distribution characteristic of background light.

这种方法假设同类物体具有类似的特征，在灰度图像中是亮度，在彩色图像中则为物体的颜色。

Procedures for the use of the VC, to achieve the dynamic image sequence background renewal function, for the need to use background processing the difference friends, this can provide a good pre-processing.

本程序使用VC++，实现了动态图像序列背景重建的功能，对于需要使用背景差分进行处理的朋友，这个能够提供很好的前期处理。

The fired nerves and the unfired nerves of PCNN corresponding to pixels of image are considered as target and the background respectively. The between-cluster variance between the target and the background is calculated at each process of iteration.

在PCNN中，具有相似输入的神经元同时发生脉冲，能够弥补输入数据的空间不连贯和幅度上的微小变化，从而较完整地保留图像的区域信息，这对图像分割无疑是非常有利的。

Set up the background gradient vectograph of highway surface at first, according to the comparative result with the gradient vectograph of the present frame image, judge whether it is highway surface background or vehicle , then carry on morphological filtering which can remedy the inside cavity and reject isolated points, and the vehicle is segmented accurately last.

首先建立路面背景梯度矢量图，根据与当前帧图像的梯度矢量图的比较结果，判断是否是路面背景或是运动车辆，然后对运动车辆区域进行形态滤波，弥补内部空洞和剔除杂点，进而准确分割出车辆。

In case of simple background, we use image difference for motion region detection, and then adopt the original Chan-Vese model for face contour detection and tracking, while in case of complex background, we use Wronskian change detector for motion region detection, and then adopt the modified Chan-Vese model for face contour detection and tracking.

对于简单背景情况，首先利用图像差分进行运动区域检测，然后在运动区域内采用Chan-Vese模型检测人脸轮廓，并根据其定位结果计算下一帧中新的运动区域和提取人脸轮廓；对于背景复杂的情况，则用朗斯基变化检测算子来首先检测出运动区域，然后在运动区域内采用改进的Chan-Vese模型检测人脸轮廓，并根据其定位结果计算下一帧中新的运动区域和提取人脸轮廓。

As of Tuesday, Google's results were still censored in China.
