Targets are extracted from the images according to their size, shape, intensity, etc. An improved method to identify every coded target is proposed. The gray scale centroid algorithm is applied to get subpixel locations of both uncoded and coded targets.

该算法首先根据标记点的尺寸、形状、灰度变化及位置分布等特征提取目标；然后利用非编码元与编码元的不同形状与灰度特征，提出一种改进的编码元自动身份识别方法，同时实现非编码元与编码元的分类；最后采用质心法进行标记点的精确定位，达到亚像素精度。

This paper brings forward a approach for textile flaw automatic detection based on optimal Gabor filters. At first the niche genetic algorithm is employed to attain the parameters of the optimal Gabor filters and segmentation threshold based on the feature of the unflawed textile,and then apply the optimal Gabor filter and threshold on the fabric image to achieve the resnlts.

为了对织物缺陷进行快速准确的自动检测，建立了一种基于Gabor滤波器的织物缺陷自动检测方法，即首先根据无缺陷织物的结构特征，应用小生境遗传算法寻找最优的Gabor滤波器参数和分割阈值；然后将待检图像通过滤波和分割来得到检测结果，同时根据响应矩阵的极小值点来计算缺陷的形状特征。

The content of each part follow as: In the first chapter, as start point and base of the paper, this part focuses on the basic study ofdefinition characteristic of NO, and the existing base of NO-E-Commerceenvironment; In the second one, this part studies the theory base of NO comprehensively applying the theories of core competence competent strategy and transaction cost; Chapter three studies the NO from the coordination of NO, and gives the structure clarification and characteristic of NO firstly, at the same time, put forward the concept of Virtual Enterprise Cluster; Based on such conclusion, studies the model of NO from life cyc organization level process and value chain, and operational mode; In Chapter four, a theoretical explanation was addressed on the above structure by modeling NO with game theory and graphic theory; In the fifth chapter, on the bases of analysis of NO operational risks, coordination mechanism of NO was studied by individually modeling the NO without core and NO with core, and then put forward the solution for coordination mechanism of NO; As an important component of coordination mechanism of NO, Chapter six explored some basic concept of trust and importantly put forward the way of how to build trust in NO, especially investigated the supporting function of valid reputation mechanism of NO for the trust building, importantly an operational method on building reputation mechanism and evaluation method in NO were given; The last chapter applied theconclusion of the paper to investigate the famous trade Web-SUNBU.
