The main contribution and valuable results of this dissertation can be listed as following:At the beginning, through analyzing the process of color image segmentation and comparing the results of "color image segmentation using fuzzy C-means and eigenspace projections" and "color image segmentation using histogram multithresholding and fusion",the advantages and drawbacks of these two methods are found.

本文研究的主要内容为：首先，对彩色图象分割过程进行分析，并对两种彩色图象分割算法即模糊c-均值和特征空间投影算法、直方图多阈值及融合算法的分割结果进行比较，从算法本身分析了其优缺点。

This paper first replaces the Euclidean distance in Otsu's thresholding segmentation method with the generalized harmonic mean distance and obtains a kind of new robust image segmentation algorithm,then the method of choosing its optimal parameter in new segmentation algorithm is brought forward.

首先将Otsu图像分割法中的欧式距离用广义调和均值距离代替并得到一种具有鲁棒性的图像分割新算法，其次给出该算法中参数选取办法。

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.

第二种方法，基于双向角度微分的边点提取法，针对三维正交模型采用基于截面线的方式组织数据，此方法比基于曲率半径方法更简洁，不用进行曲面拟合，大大提高了计算速度；计算过程中由数据点的直接差分逼近微分，但直接差分对数据误差敏感，为此，本文提出了阈值过滤的方法，一方面过滤了数据误差在计算结果中引起的噪音，另一方面可以按照设计意图控制边点的提取；来决定是否提取光滑交接的边点。

Video object segmentation can be divided into automatic segmentation and semiautomatic segmentation according to the user-assisted degree.

Non-uniform illumination may cause wrong segmentation in the threshold segmentation of image. To overcome the above problem, a novel irradiant compensation algorithm for image segmentation is presented.

针对受到光照不均匀影响的图片在直接进行阈值分割造成的错分割问题，提出了在分割前对图像进行光照补偿的预处理，从而降低光照不均匀对阈值分割造成的不利影响。

Color image segmentation is of great importance to the classification of cells. The thesis emphasizes on the research of segmentation algorithm of color images, which includes the segmentation of karyon and cytoplasm.

彩色细胞图像的分割是细胞分类的关键因素，其分割算法是本文的研究重点，包括细胞核的分割与细胞浆的分割两个部分。

Customer segmentation is a critical step to the success of target or segment marketing. The effectiveness of customer segmentation depends on a good number of variables such as customers' demographic, behavioral, geographic, and psychographic characteristics. However, the huge combinations and correlations among variables make customer segmentation a challenging task, even with the aids of information technologies. The industry is desperate for effectual and powerful tool for excavating customer knowledge from the large accumulated data in the corporate database management system.

摘要顾客分群对於目标行销或市场切割的成功与否都是一个重要的关键步骤，顾客分群结果的优劣取决於其所采用的分群因子，顾客分群中常使用的分群因子有顾客的人口统计资讯、行为特徵、地理性资讯与心理方面的特徵等，然而，这大量与因子复合交错的资讯使得顾客分群成为企业的一个挑战，并且渴望寻求一个能够从大量累积的资料库系统中挖掘知识的工具。

In video sequences, the objects we are interested in are those which are of self-movement, so most of video segmentation refer to the segmentation of self-movement objects. This paper also mainly discusses the segmentation of self-movement objects.

由于在视频序列中，人们注意及感兴趣的主体，一般是具有自主运动的物体，所以现有的视频分割算法绝大多数指的是视频中运动对象的分割，本文也主要讨论视频中运动对象的分割。

D entropic thresholding method is a common image segmentation technology,it is suitable for the image segmentation of the object and background occupying the vast majority region of 2-D histogram,but this approach neglects the information of edge regions to the results of the segmentation.

二维熵的图像分割方法是一种常用的阈值分割技术，适合于对象和背景占据二维直方图绝大部分区域的图像分割，但该方法忽略了边界区域的信息对分割结果的影响。

For the accurate segmentation of the nucleus,the conventional iterative threshold segmentation are improved.

在灰度空间，通过改进的迭代阈值分割算法，对白细胞的胞核进行了精确的定位和检出。

We stopped by the old fashion ice cream parlor Manhattan Beach Creamery for some refreshment. The "No Shoes, No Shirt, No Problem" sign on the wall epitomizes the beach lifestyle.

我们去商店区的一家老式冰淇淋店坐坐，墙上挂著「没鞋，没上衣，没问题」的牌子完全捕捉了海滩生活的随性及风格。

"If therefore", argues Bellarmine we can offer our prayers and our satisfactions in behalf of those detained in purgatory, because we are members of the great body of Christ, why may not the Vicar of Christ apply to the same souls the superabundant satisfaction of Christ and his saints--of which he is the dispenser?

" "因此，如果"，认为贝拉明（德indulgentiis ，十四）"我们可以提供我们的祈祷和我们满意的代表那些被拘留在炼狱，因为我们是成员的伟大基督的奥体，为什麼可能不是牧师基督适用於同样的灵魂满意的过剩是耶稣和他的圣人-他是在配药？
