On the basis of the image correlation and the nonparametric kernel density estimation, kernel density functions of background and foreground were built., Bayesian theory was used to estimate the prior probabilities of the foreground and the background, so an estimative threshold was obtained and the classification of the background and the foreground was realized.

首先，在图像相关性的基础上，利用非参数核密度估计的方法，建立前景和背景的核密度函数，再利用贝叶斯理论，估计出背景和前景的先验概率，两者相结合得到一个估计的阈值，从而实现目标和背景的分类。

Part two draws out the discusssion about the exotic background with an argument in the acadame circle. The investigation considers that Greene made the exotic background a special space and place with a spiritual characteristic of the modern society to express his cultural acknowledge and consideration about the modernity.And with the combination to the religious sense, the exotic background gains an ontological significance.

第二部分以学界争论引出人物生存语境即人物背景的讨论，指出此异域背景的精神性特征，以及格林将异域作为现代社会中的特殊空间，寄寓了他个人对时代的文化认知和思考，而将异域和宗教意识的结合则为背景提供了存在本体论范畴的含义。

The stress was the study of the new methods of calculation the harmonic voltage and the harmonic current, and a new concept of filter ratio to evaluate the actual effect of single harmonic filter was raised considering the background harmonics. As well, the calculation mode of the single harmonic filter was also given based on the concept of filter ratio; it can offer effect data to evaluate the actual filter ratio of the single harmonic filter. At the same time, a method of designing the single harmonic filter was given, too, considering the background harmonics of the power system. In this paper, both the computer analysis and the proven had been done. And the result was shown to be that the voltage aberration and the harmonic current were decreased, and that the actual filter ratio of single harmonic filter was raised. The reason that we must consider the background harmonics when designing a single harmonic filter was also expatiated in this paper.

重点研究了考虑电网背景谐波下谐波电压、电流的计算方法，提出了用滤波率来评价单调谐滤波器安装容量利用率的概念，基于滤波率，分别给出了不考虑、考虑电网背景谐波时，单调谐滤波器的计算模型，为定量分析和评价单调谐滤波器的实际补偿效果提供了依据：并以此提出了考虑电网背景谐波的单调谐滤波器计算机辅助优化设计方法，并经计算机仿真分析、论证，减少了负载母线谐波电压畸变率和注入系统的谐波电流，有效地提高了单调谐滤波器的滤波效果，阐述了单调谐滤波器的设计过程中要考虑电网背景谐波的理论和实际意义。

If a cluster were moving faster or slower than the universe's background radiation, you'd expect to see the background heated slightly in that region of the universe-the result of a sort of electron-scattering "friction" between the cluster's hot gas and particles in the background radiation.

如果星系群的运动快于或慢于宇宙背景辐射，你可以预期看到在这宇宙附近背景被略微加热，这是散射电子在星系群的热气流和背景辐射粒子之间摩擦产生的结果。

A fast extraction method of beer bottle rasied character is introduced in this paper. It is the technique combination of moving target tracking based on dynamic image sequence with edge detection algorithm for speeding up the processing of character extraction to meet the demand of on-line detection in industry. First dynamic image sequence is obtained with an area CCD camera, and the background frames are detected based on the coherence between the background and character image from the video and inevitability of background frames emergence.

运用基于动态图像序列的运动目标跟踪技术，结合图像边缘提取理论中的检测算子模板，提出了一种快速提取啤酒瓶凸性字符的方法：首先采用单个面阵CCD得到啤酒瓶字符的运动图像序列，然后利用背景在运动图像序列中的镜头突变性和出现的必然性，检测视频流中的背景帧，最后采用基于边缘检测的背景配准方法，得到运动图像和校正背景图像的差分图像，恢复出真正的运动物体。

At the same time, it produced a series of imaginings that became deeper and deeper – it was like a hypothetical point that allowed me to be completely immersed in the actual cultural background. Various human weaknesses have certain solemn and stirringly dramatic elements. In order to adapt to the basic visual experience, in order to allow the audience to easily accept and enjoy the underlying elements of the work, I intentionally left white spaces, they looked like hints in a guessing game. The viewer who understands would have a good laugh after becoming suddenly enlightened. This enables the viewer and me to have a sort of conspiratorial relationship, its meaning does not reside in the painting itself, but in the shared cultural background of myself and the audience as well as the shared attitude of such a cultural background. This makes it believable, a hidden bridge, often in a somewhat clear yet somewhat mysterious moment, two strangers who have never met are able to achieve a profound understanding, like that happiness of suddenly catching someone when playing hide and seek as a child ...

同时，阐发了一系列的联想，并使之不断地深入，它就像一个假设的点，将我置身于整个现实文化背景之中，这里人的种种缺陷带有某种悲壮成分的戏剧性，为了适应基本的视觉经验，为了使观众一目了然地接受并乐于体味作品中的潜在因素提供某种线索，我留有一些空白，它类似猜谜游戏中的启示，能使会心的观众茅塞顿开后一场哑然失笑，能使我和观众之间形成一种合谋关系，其意义不在画面本身，而在于我和观众之间存有共同的现实文化背景，以及对这种文化背景所持有的共同态度，它也就是有了可信性，就像冥冥中桥梁，常常在时而明晰时而神秘的一瞬，两个素昧平生的陌生人之间突然达到了心领神会的境地，如同儿时捉迷藏游戏中突然捉到对方时的开心……。

For every one of my New Year resolutions, I have been a backslider for years.
