可分割

This illuminates that why EVC can overwinter in aberrance and be epidemic next year again.

进一步在理论上阐明可控制滤波器作为分割的速度项的可行性。

The effectiveness and accurateness of this method have been proved by experimentalresults.

这种多层次图象目标与背景快速分割的思想也可用于其它类似场合。

The adaptiveness of the approach has been tested by simulations on a wide range of images.

根据Fu等在文献 [1 ]中的综述，用于图像分割的方法可分为特征阈值

Image segmentation ; active contour model ; variational calculus ; level set methods ; additive operator splitting scheme

图像分割；活动轮廓模型；变分方法；水平集方法；可加算子分裂算法

This paper puts forward a useful image segmentation method that can be applied to extract objects with different gray levels.

摘要本文提出了一种较为实用的，可用于多灰度层次目标提取的分割方法。

By using network flow theory, the optimization problem of power conservation is transformed into the optimal bipartition problem of a flow network which can be partitioned by the max-flow mm-cut algorithm.

利用网络流理论，将节约电量的最优化问题转化为一个流网络的最优分割问题，而后者可采用最大流最小切割算法实现最优切分。

The film or movie is the most popular and common video resource. In this paper we use the film video as an example, aims to implement real-time retrieve of explosion and shot scenes, has carried on the following research mainly: first, we proposed a method of real-time recognition of explosions based on dominate-color and audio information and improved the accuracy the retrieve;second, we proposed a method of real-time retrieve of shots scenes based on audio information and differences between frames when the shot occurs;third,a whole video abstraction system is proposed, it can cut off the clips which have been retrieved and merge them into a independent video abstraction in the same time edit the information of the it ;forth, it offers two-level retrieval structure of"key frame-highlights"and can play segmentation result and the whole video just like a video player.

电影或电视剧视频是人们日常生活中最喜闻乐见也是最常见的视频内容，本课题以此类视频为研究素材，目的是实现实时爆炸和枪击场景的检测，主要进行了以下几个方面的研究：1针对视频中爆炸场景的主色和音频特点，提出了一种基于声像特征的实时爆炸场景检测算法；2捕捉视频中枪击事件瞬间的帧间变化信息和相应音频信息，提出了一种基于声像特征的实时枪击场景检测算法；3从原始视频中切割检索到的精彩视频场景合并成单独精彩缩略视频，并可进行相关信息编辑，形成比较完备的视频摘要系统；4形成关键帧-精彩视频场景的二级浏览结构，可对分割结果或整个视频片断进行播放，基本实现播放器的功能。

The induced rate of rooting with naphthaleneacetic acid was higher than indolebutyric acid. The medium supplemented with 50 mg/l ascorbic acid and 0.5 mg/l NAA could improve the growth and development of root system. 57.5% of shoots could develop to the well-rooted plantlets and develop into healthy and fertile plants when planted in soil.

将芽体分割进行发根试验的结果显示，naphthaleneacetic acid诱导根系的效果优於indolebutyric acid，添加50 mg/l抗坏血酸和0.5 mg/l NAA之培养基则有更好的效果，约有57.5%的芽体可再生成具有旺盛根系的植株，经移植至土壤中也可生长健旺及正常开花。

Results: The pulmonary arteries could be recognized in CVH images and reconstructed. The three-dimensional images perfectly show the brunches of the pulmonary arteries, even the subsubsegmental arteries were able to be recognized. Conclusion: The research reconstructed and visualized the pulmonary arteries of the first Chinese Visible Human.

结果：CVH肺脏断面图像清晰，可清楚显示肺动脉系统，分割后重建出肺内动脉系统，重建图像质量较高，最远可显示肺动脉的第5级分支。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
