时间分割

Abstract］ Objective To explore the effect of radiotherapy on the auxesis of Hela cell in cervix carcinoma to offer the theory elements to identify whether or not the cervix carcinoma would be treated by radiotherapy with non-routine segmentation.Methods After radiotherapy with different doses,the Hela cells changes of potential doubling time by cytometry with trypanblau coloration were analysed,and the livability of clonogenic cell at the same time was detected by clone,and the two former were combined to aralyse the changes.

This text mainly is to panorama video frequency picture, the usage partitions new calculate way automatically according to the video frequency object of timespace consociation at preparing processing stage's ash to video frequency sequence degree diagram to carry on a partial contrast degree to strengthen a processing, increasing foreground object and the contrast degree of background, the filter which passes 3 ×s 3 templates filters in addition to contrast degree strengthen after of lead go into of a little amount 噪 voice;Then aim at the circumstance of complicated background, the calculate way in the text puts forward the covariance characteristic backlog which makes use of immediately signal to get the background that the calculate way needs, overcoming the irregularity that the handicraft obtains background, carrying out a background information to obtain automatically;The standpoint put forward a background backlog finally to categorize a discussion in the process, solved object stop sport time is longer result in the partition throw the problem for losing.

本文主要是对全景视频图像，运用基于时空联合的视频对象自动分割新算法，在预处理阶段对视频序列的灰度图进行局部对比度增强处理，增加前景物体与背景的对比度，通过3×3模板的滤波器滤除对比度增强后的引入的少量噪声；然后针对复杂背景的情况，文中的算法提出利用随即信号的统计特性积累得到算法所需的背景，克服手工获取背景的弊端，实现背景信息的自动获取；最后提出背景积累过程中分类讨论的观点，解决了物体停止运动时间较长时造成分割丢失的问题。

Then applied the new algorithm to a number of natural images.

Aimed at some shortages in the existing methods based on piecewise polynomial representation, such as sensitive to noise awl lower computational efficiency, a robust method of optimal segmenting time series is proposed.

针对分段多项式回归方法存在计算效率低和对噪声较敏感等缺点，提出了具有稳健性的最优分割方法，以解决时间序列数据相似搜索及知识发现处理中的长时间序列分割问题。

With SplitMovie, you can split, cut and trim your video automatically by size, time or number of segments, or manually by selecting the beginning and end points of the selected segments.

使用 SplitMovie，你可以按炤尺寸，时间或者片断数量自动地分割你的视频文件以及通过选择所需要的视频片断的开始和结束点手动地进行分割。

It can also split the files accordingto the same setting time and split cyclically.

该软件还可以根据相同的时间设置和分割周期分割文件。

To avoid over-estimating capacity, this study divides production scheduling horizon into many small segmented buckets. To reflect the time-varying property of demands, this study decides initial production order by using "run out time of the inventory" proposed by Leachman.

为了反应需求率随时间改变的特性，将生产时期以避免高估产能的方式分割为数个分割时段，依据Leachman所提出的存货耗尽时间成本决定起始生产顺序。

In the experiment, the FSH+LH combinations were adopted to superovulate KM mice to ascertain the proper phase to gain morulae and blastocysts, three ways were adopted to split the morulae and blastocysts, demi-embryos were cultured in D-PBS, mTCM199, CZB, mM16 added with FCS or MS of different concentration, and transplantation of the blastocysts derived from demi-embryos was performed.

本试验以昆明白小鼠为实验动物，试采用FSH和LH进行超排处理，确定了该处理程序下获取桑椹胚、囊胚的恰当时间，比较了三种方法对桑椹胚和囊胚分割的效果，采用了添加不同浓度FCS、MS的4种培养基对分割胚进行体外培养，并进行了半胚移植。

In this algorithm, first, the time series is segmented and symbolized with the linear segment representation and the vector shape clustering method,so that each symbol can represent aprimitive and independent pattenr.Thenthe minimal occurrence representaion of time series and the association rule discovery algorithm proposed by Agrawal is combined to extrac frequent patterns of various structures from non-synchonous multiple time series.

该算法首先利用线性化分段表示法和矢量形态聚类实现时间序列的特征分割与符号化转换，然后通过将Agrawal关联模式发现算法的核心思想与时间序列最短实现表示方法相结合，实现了非同步多时间序列中多种结构频繁模式的发掘。

Thirdly, it introduces the theory of the imagesegmentation and frequent segmentation technique. The aim of the imagesegmentation is to mark off the interested region of the image, which is done to thecorresponding image processing to reduce the operation time and save the storagespace. At last, it mostly introduces the compress technique based on the wedgelet, andcompares the CART model which is introduced by Donoho and the improved modelby Romberg et.al. with the model of the article, then compares the image ofprocessing based on the three methods.

然后，介绍了图像分割理论和常用的分割技术，图像分割的目的是划分出感兴趣的图像区域，进行相应的图像处理，减少运算时间和节省存储空间；最后，主要介绍了基于伸长小波压缩的技术，将目前主要的算法----Donoho提出的CART模型和Romberg等人基于此的改进模型，与本文所提出的算法模型进行了比较，并对三种方法处理的效果图作了详细的比较。

Further more, the simplified analysis method on stressed-skin effect of corrugated steel sheet is also discussed in detail.

此外还比较详细地探讨了蒙皮效应的简化分析方法。
